⦁ Exactly one defective I-phone?
⦁ Exactly two defective I-phones?

Answer by ewatrrr(24785) (Show Source): You can put this solution on YOUR website!
p = 4/300 = 1/75 = .0133
n = 20
TI syntax for P(x-value) is binompdf(n, p, x-value).
⦁ Exactly one defective I-phone? p = binompdf(20, .0133, 1) = .2062
⦁ Exactly two defective I-phones? p = binompdf(20, .0133, 2) = .2064
⦁ Exactly three defective I-phones? p = binompdf(20, .0133, 3)= .0023
⦁ Exactly four defective I-phones? p = p = binompdf(20, .0133, 4)= .0001
