Question

Within the United States, approximately 11.25% of the population is left-handed. Of the males, 12.6% are left-handed, compared to only 9.9% of the females. Assume that the probability of selecting a male is the same as selecting a female. If a person is selected at random, to find the probability that the selected person is a right-handed female, one would compute:

Answer 1

Answer:

There is a 45.05% probability that the selected person is a right-handed female.

Step-by-step explanation:

We have these following probabilities

A 50% probability that a person is a male

A 50% probability that a person is a female.

A 12.6% probability that a male is left-handed.

A 9.9% probability that a female is left-handed.

If a person is selected at random, to find the probability that the selected person is a right-handed female, one would compute:

50% are female.

9.9% of the females are left-handed, so 100-9.9 = 90.1% of the females are right handed.

So

$P = 0.5*0.901 = 0.4505$

There is a 45.05% probability that the selected person is a right-handed female.
