Question

a card is drawn from a deck of 52 playing cards. find the probability of drawing a king or ared card.

Answer 1

 There are 26 red cards, two of which are KINGS, The remaining two KINGS results
 in a total of 26 + 2 = 28 possible draws.

  P = 28 ⁄ 52 = 7 ⁄ 13 = 0.538

Answer 2

probability of a King = 4 / 52 = 1/ 13
probabiliity of a red card = 26/ 52 = 1/2
Prob of a king or a red card
1/ 13 + 1/2 =15 / 26

Answer 3

King would be a 4 out of 52 probability, or 1 out of 13
Red would be 26 out of 52, or 1 out of 2

Answer 4

P ( A ) = P ( king ) = 4/52 = 1/13
P ( B ) = P ( red card ) = 1/2

P ( A U B ) = 1/13 + 1/2 - [ 1/26 ]
P ( A U B ) = 2/26 + 13/26 - [ 1/26 ]
P ( A U B ) = 14/26 = 7/13

Answer 5

26 red cards plus 4 kings so its 30/52

Answer 6

Since you have already pulled a red card (heart), that leaves the following scenario 26 black cards out of 51 cards remaining. P = 26/51

Answer 7

28/52 simplified 7/13
