Explanation / Answer

16) n = 15

p = 0.4

P(none has a cell phopne or a laptop) = (1-0.4)15 = 0.00047 = 0.000

17) n = 10

p = 0.05

P(at least 6 are defective) = P(6) + P(7) + P(8) + P(9) + P(10)

= 10C6x0.056x0.954 + 10C7x0.057x0.953 + 10C8x0.058x0.952 + 10x0.059x0.95 + 0.0510

= 0.0

18) n = 5

p = 0.05

P(3 are defevtive) = 5C3 x 0.053 x 0.952

= 0.001
