Given : The U.S. Energy Department states that 60% of all U.S. households have ceiling fans.
In addition, 29% of all U.S. households have an outdoor grill.
Suppose 13% of all U.S. households have both a ceiling fan and an outdoor grill.
A U.S. household is randomly selected.
To Find : What is the probability that the household has a ceiling fan or an outdoor grill?
Solution:
ceiling fans. = 60 %
outdoor grill. = 29 %
both a ceiling fan and an outdoor = 13 %
a ceiling fan or an outdoor grill = ceiling fans. + outdoor grill. - Both
= 60 % + 29 % - 13 %
= 76 %
probability that the household has a ceiling fan or an outdoor grill = 76 %
= 76/100
= 19/25
= 0.76
