Explanation / Answer

3) P = 0.35

n = 16

A) P(3 < x <8 ) = P(X = 4) + P(X = 5) + P(x = 6) + P(X = 7)

= 16C4 * (0.35)4 * (0.65)12 + 16C5 * (0.35)5 * (0.65)11 + 16C6 * (0.35)6 * (0.65)10 + 16C7 * (0.35)7 * (0.65)9 = 0.71

B) P(x < 4) = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3)

= 16C0 * (0.35)0 * (0.65)16 + 16C1 * (0.35)1 * (0.65)15 + 16C2 * (0.35)2 * (0.65)14 + 16C3 * (0.35)3 * (0.65)13

= 0.13
