Question

What is the probability that you pull a red 6 or a heart from a standard deck of cards?

Answer 1

There are 52 cards in a standard deck, 2 red six, 13 hearts

P(Red 6) = 2/52

P(a heart) =13/52

Among the red 6's, there is one heart, therefore:

P(red 6 and a heart) =1/52

Using the probability formula for non-mutually exclusive events:

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

P(red 6 or a heart) = P(red 6) +P(a heart) - P(red 6 and a heart)

=2/52 +13/52 -1/52

=14/52 = 7/26
