Printed circuit cards are placed in a functional test after being populated with semiconductor
chips. A lot contains 120 cards, and 15 are selected without replacement for functional testing. If
15 cards are defective, what is the probability that at least 1 defective card is in the sample?
Let X denote the number of cards in the sample that are defective. Then, X has a hypergeometric
distribution. (Show solutions)
a. 0.0356
O b. NONE
O c. 0.1177
O d.0.8823
