I need explanation please

Answer 1

7/13

Explanation:

There are 5 even numbers per suit (2, 4, 6, 8, 10), and 4 suits, for a total of 20 even number cards.

There are 13 hearts.

There are 5 hearts that are also even numbers.

P(A or B) = P(A) + P(B) − P(A and B)

P(A or B) = 20/52 + 13/52 − 5/52

P(A or B) = 28/52

P(A or B) = 7/13
