The City College football team consists of seven freshmen, eight sophomores, sixjuniors, and nine seniors. Four of them will be selected at random and given a drug test. Giventhat none of the selected players are seniors, what is probability that at most two freshmen areselected for the test?

0.9123 or 91.23%

Step-by-step explanation:

Given that none of the selected players are seniors, there are 7 freshmen, 8 sophomore and 6 juniors left (total of 21 players). Since four players are selected, the probability that at most two freshmen are selected is 100% minus the probability that either 4 or 3 freshmen are selected:

The probability is 0.9123 or 91.23%

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
