Verified Answer
In a box containing 100 Ipods, 10 are defective. The probability that ...
r = 1, n = 5
p = 10/100 = 1/10,
q = 1 - p
q = 1 - 1/10 = 9/10
= nCr (p)r (q)(n - r)
Exactly one is defective = 5C1 (1/10)1 (9/10)(5 - 1)
= 5C1 (1/10) (9/10)4
= (1/2) (9/10)4
p = 10/100 = 1/10,
q = 1 - p
q = 1 - 1/10 = 9/10
= nCr (p)r (q)(n - r)
Exactly one is defective = 5C1 (1/10)1 (9/10)(5 - 1)
= 5C1 (1/10) (9/10)4
= (1/2) (9/10)4
