The probability that a new driver passes their drivers test on the first time is 0.583 . Five people are randomly chosen, a. what is the probability that 3 of them get their license the first time
P(X=0) = 5C0(0.583)0(0.417)5 = P(X=1) = 5C1(0.583)1(0.417)4 = P(X=2) = 5C2(0.583)2(0.417)3 = P(X=3) = 5C3(0.583)3(0.417)2 = 0.345
P(X=4) = 5C4(0.583)4(0.417)1 = P(X=5) = 5C5(0.583)5(0.417)0 = 4

The probablity that a randomly selected student lives in Renous is 0.31. given that 5 students are randomly selected, what is the probability that:
a. 0 live in Renous P(x=0) = C (0.31) (0.69) = 0.1564
b. 1 lives in Renous P(x=1) = C (0.31) (0.69) = 0.3513
c. 2 lives in Renous P(x=2) = C (0.31) (0.69) = 0.3157
d. 3 lives in Renous P(x=3) = C (0.31) (0.69) = 0.1418
e. 4 lives in Renous P(x=4) = C (0.31) (0.69) = 0.0319
f. 5 lives in Renous P(x=5) = C (0.31) (0.69) = 0.0029
