An ordinary deck of playing cards has 52 cards. there are four suits spades, hearts, diamonds, and clubs, with 13 cards in each suit. spades and clubs are black; hearts and diamonds are red. if two of these cards are selected at random, what is the probability that the card selected is a spade then a black face card?

Consider a bag that contains 220 coins of which 6 are rare indian pennies. for the given pair of events a and b, complete parts (a) and (b) below. a: when one of the 220 coins is randomly selected, it is one of the 6 indian pennies. b: when another one of the 220 coins is randomly selected (with replacement), it is also one of the 6 indian pennies. a. determine whether events a and b are independent or dependent. b. find p(a and b), the probability that events a and b both occur.
