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. If5cardsaredefective, what is the probability that at least 1 defective card appears in the sample?

c. Calculate mean and variance of the number of defectives in the sample when 5 cards are defective.
