A card is drawn from a standard deck of cards. What is the probability that your
card is a red card or a king.

Sagot :

Answer:

a standard crd deck has 52 cars so

the probability of getting red is 0.5 since 2 of the 4 faces are red. The probability for getting a king is 1/13 since there are 13 different card values.

Step-by-step explanation:

Note:

52 cards in a deck

26 red cards in a deck

4 kings in a deck


Let’s set:

P(A) = drawing a red card
P(B) = drawing a king card

P(A or B) = drawing a red or a king card

P(A and B) drawing a red AND a king card

Formula:
P(A or B) = P(A) + P(B) - (A and B)

Solve:
P(A and B) = 26/52 • 4/52 = 1/26

P(A or B) = 26/52 + 4/52 - 1/26 = 7/13

Your answer is 7/13.
