Explanation / Answer

28.

Let C be event of a faulty switch

D be a event of a defective chord

P( C or D) = .06

P(C) = .026

P(C and D) = .008

P(D) = ?

We know :

By the law of probability: P(C or D) = P(C)+P(D)-P(C and D)

.06 = .026+P(D)-.008

P(D) = .06-.026+.008 = .042

Hence, the probability that a coffee maker will have defective cord is .042
