Question

What is the probability that is a heart and a queen?
What is the probability that is a heart given it is a queen?
What is the probability that is a queen given it is a heart?

Answer 1

The probability of getting either a heart or a queen is 4/13

Solution:

The probability of an vent is given as:

In a deck of 52 cards, we have to find the probability of getting either a heart or a queen

Therefore,

Total number of possible outcomes = 52

Favorable outcome = getting either a heart or a queen

Number of queen in deck cards = 4

Number of heart = 13

Already 1 queen is present in heart

Therefore,

Favorable outcome = 4 + 13 - 1 = 16

Thus,

Thus the probability of getting either a heart or a queen is 4/13

Answer 2

Step-by-step explanation:

There are 4 Queens, 13 Hearts, and 1 Queen of hearts in a standard deck of 52 cards. Thus, P(E1) = 4/52, P(E2) = 13/52, and P(E1 ∩ E2) = 1/52. Thus, the probability of drawing a Queen or Heart is 4/52 + 13/52 - 1/52 = 16/52.
