What is the probability that a card selected at random
from a standard deck of 52 cards is an ace or a heart?

Solution

number of aces =4

P( ace )=4/52

number of hearts= 13

p(heart) =13/52

number of ace that is heart

=1/52

probability that a card selected at random
from a standard deck of 52 cards is an ace or a heart

=p(ace)+p(heart) -p(ace and heart)

=4/52 +13/52 -1/52

=16/52

=4/13
