Question 1185555: If one card is drawn from an ordinary deck of cards, find the probability of getting
each event:
(a) A 7 or an 8 or a 9
(b) A spade or a queen or a king
(c) A club or a face card
(d) A 9 or a 10 or a spade or a club
Answer by greenestamps(13198) (Show Source): You can put this solution on YOUR website!
(a) A 7 or an 8 or a 9
4 7's, 4 8's, and 4 9's, so a total of 12. P=12/52 = 3/13
(b) A spade or a queen or a king
13 spades; 3 queens that are not spades; 3 kings that are not spades -- total 19. P=19/52
(c) A club or a face card
13 clubs; 3*3=9 face cards that are not clubs -- total 22. P=22/52 = 11/26
(d) A 9 or a 10 or a spade or a club
4 9's and 4 10's; 11 spades that are neither 9 or 10; 11 clubs that are neither 9 or 10 -- total 30. P=30/52 = 15/26
OR...
13 spades; 13 clubs; 2 9's that are neither spade not club; 2 10's that are neither spade not club -- total 30. So again P=30/52 = 15/26.
