A single card is drawn from a deck. find the probability of selecting a heart or a 9.

Solution:

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

Number of cards in a deck = 52

We need to find the probability of selecting a heart or 9.

Probability of heart = 13/52

Probability of nine = 4/52

Probability of nine in heart = 1/52

Probability of selecting a heart or nine = 13/52 + 4/52 - 1/52

= 17/52 - 1/52

=16/52

=4/13

Therefore, the probability of selecting a heart or 9 is 4/13.

A single card is drawn from a deck. find the probability of selecting a heart or a 9.

Summary:

A single card is drawn from a deck. The probability of selecting a heart or a 9 is 4/13.
