# Question: Printed circuit cards are placed in a functional

Printed circuit cards are placed in a functional test after being populated with semiconductor chips. A lot contains 140 cards, and 20 are selected without replacement for functional testing.

(a) If 20 cards are defective, what is the probability that at least 1 defective card is in the sample?

(b) If 5 cards are defective, what is the probability that at least 1 defective card appears in the sample?
