4.A card is selected from an ordinary deck of 52 cards. Find the probabilities for each of the following: (a) A red card (f) A face card or a club (b) A face card (g) A face card and a club (c) A red card or a 10 (h) Not a face care and not a club (d) A queen (e) Not a queen A)There are 26 red cards, so the probability the card is red is 26/52 = ½ B) The probability of getting a face card is 16/52=4/13 C) The odds of randomly picking either a red card or a 10 card from a standard shuffled deck of cards is about 53.85%. So just over half of the time this will happen. P(10 OR R) = P(10) + P(R) - P(10 AND R) P(10) = 4 / 52 P(R) = 26 / 52 P(10 AND R) = P(getting red tens) = 2 /52 P(10 OR R) = (4/52) + (26/52) - (2/52) = 28/52 half are red, so 26 plus the 2 black 10's=28 28/52 D) There is a 4 in 52 chance that you will pick a queen from a deck of cards E)There are 48 non queen cards in the deck so the chances of getting a “non queen” is 48/52 F) We must be careful about double counting. There are 12 face cards and 13 clubs,
