As we already found, the probability of winning for any selection is 1/3 = 0.333.
What is probability?Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favourable outcomes / Number of samples
a) Let's suppose that player 1 chooses rock, and the selection of player 2 can be thought of as random.
If player 2 randomly selects rock, the result of the game is a draw.
if player 2 randomly selects papers, player 1 loses.
if player 2 randomly selects scissors, player 1 win.
Then we have 3 options with the same probability, that will be:
1/3
This is, the probability of winning is equal to the quotient between the number of outcomes that make player one win (1, in this case, scissors) and the total number of outcomes (3) = 1/3
the probability of a draw is equal to the quotient between the number of outcomes that make a draw (1, in this case, rock) and the total number of outcomes (3) = 1/3
The probability of losing is equal to the quotient between the number of outcomes that make player one lose (1, in this case, paper) and the total number of outcomes (3) = 1/3
The complete question is given below.
2. Almost everyone has played the rock-paper-scissors game at some point. Two players face each
other and, at the count of 3, make a fist (rock), an extended hand, palm side down (paper), or a
"V" with the index finger and middle fingers (scissors). The winner is determined by these rules:
rock smashes scissors, paper covers rock, and scissors cut paper. If both players choose the
same object, then the game is a tie. Suppose that Player 1 and Player 2 are both equally likely to
Choose rock, paper, or scissors.
a) Give a probability model for this change process.

How many whole groups of 25 out of 90
GIVE AN EXPLANATION PLEASE
Answer: 3
Step-by-step explanation:
25+25+25=75 90-75= 15
So 25 can only go into 90 3 times evenly.
Answer:
Step-by-step explanation:
Simple, 90 / 25 = 3.6 · 90 ÷ 25 = 3.6 · 90 over 25 = 3.6 · ⁄25 = 3.6
If you want this to be like you did not look it up and actually put work towards it then put this:
ninety divided by twenty five equals 3.6, then i checked myself by multiplying 3.6 towards 90 and it had given me 25. The amount of groups that can go in would be 3.

There is a bag filled with 5 blue, 4 red and 3 green marbles. A marble is taken at random from the bag, the colour is noted and then it is replaced. Another marble is taken at random. What is the probability of getting 2 the same colour?
The probability of getting 2 the same color is 9/11.
What is probability?
According to the probability formula, the probability of an event occurring, or P(E), is equal to the proportion of positive outcomes to all outcomes. P(E) is defined mathematically as favorable outcomes divided by total outcomes. Mathematical branch known as probability deals with determining the possibility of an event occurring. Here using probability we can also calculate combination .
Here the total number of marbles are,
=>Total marbles = Blue + Red + Green
=>Total marbles = 5 + 4 + 3
=>Total marbles = 12
Then, Probability of a green = 3/12
=> Probability of not green = 1 - 3/12 = 9/12=3/4
To get exactly one green in two draws, we either get a green, not green, or a not green, green
=>First Draw Green, Second Draw Not Green
=> 1st draw: Probability of a green = 3/12
In 2nd draw: Probability of not green = 9/11 <-- 11 since we did not replace the first marble
To get the probability of the event, since each draw is independent, we multiply both probabilities
=> Probability of the event is (5/12) * (9/11) = 45/132
First Draw Not Green, Second Draw Not Green
=>1st draw: Probability of not a green = 9/12
=>2nd draw: Probability of not green = 7/11 <-- 11 since we did not replace the first marble
To get the probability of the event, since each draw is independent, we multiply both probabilities
=>Probability of the event is (9/12) * (7/11) = 63/132
To get the probability of exactly one green, we add both of the events:
First Draw Green, Second Draw Not Green + First Draw Not Green, Second Draw Not Green
=> 45/132 + 63/132 = 108/132=9/11.
Hence the probability of getting 2 the same color is 9/11.

An unstretched hanging-spring is 50 cm long. Suspending a 100-N block from it increases its length to 60 cm. Adding another 100-N block makes the spring's new length
70 cm
The new length of the unstretched hanging-spring is 70 cm.
Define the term Hooke's law?Hooke's law states that the spring's length change as a result of a compressive or tensile load is directly proportionate to the size of the force placed on the spring. Mathematically,
F = kx
Where;
K is the spring constant, while x represents the spring's length change.
As per the question-
L is the spring's uncompressed length: L = 0.5 m
Weight F1 linked to the spring: F1 = 100 N
First weight's effect on elongation x1: 60 - 50 = 10 = .01 m.
As per the Hooke's law;
F1 = Kx1
K = F1/X1
K = 100 / 0.1
K = 1000 N/m
Spring constant = 1000 N/m.
For the added 100-N block.
F = Kx2
x2 = F/K
x2 = 100 + 100 / 1000
x2 = 0.2m
x2 = 20 cm
L = 50 + 20 = 70 cm.
Thus, new length of the unstretched hanging-spring is 70 cm.

Donnie has a pool and recently discovered a leak. He continues to patch the leak until someone can come out to repair it. After all the water has completely drained out of the pool due to the patch coming off, it takes him two days to fill the pool back up. It takes three days for the pool to drain completely. How long would it take to fill the pool if the patch is off while Donnie is refilling it?
The time it will take to fill the pool if the patch is off while Donnie is filling it, found using the combined filling rate is 6 days.
What is a flow rate?A flow rate is the fluid volume that passes a specified area within a unit of time.
The number days it takes to fill the pool = 2 days
The number of days it takes for the pool to drain = 3 days
The rate at which the pool fills = [tex]\dfrac{1}{2}[/tex] per day
The rate at which the pool drains = [tex]\dfrac{1}{3}[/tex] per day
The number of days it will take the pool to fill while the patch is off is found from the combined filling rate as follows;
The combined filling rate is [tex]\dfrac{1}{2} -\dfrac{1}{3} = \dfrac{3-2}{6} = \dfrac{1}{6}[/tex]
The combined filling rate can be taken as a combined flow rate.
The combined filling rate for filling the pool while the patch is off is [tex]\dfrac{1}{6}[/tex], which is a 6th of the pool is filled per day, therefore, it takes 6 days to fill the pool while the patch is off.
