Printed circuit cards are placed in a functional test afterbeing populated with semiconductor chips. Suppose that there are 8blue credit cards, 6 red credit cards and 4 blue debit cards in abox. It is known that color and card type are to be independentwhen a card is selected at random from this box.
a) How many red debit cards must be present?
b) Suppose that, 5 cards are randomly selected in a row withreplacement. What is the probability that 2 blue credit cards and 2blue debit cards are selected?
c) Suppose that, 5 cards are randomly selected in a row withoutreplacement. What is the probability that 2 blue credit cards and 2blue debit cards are selected?
