Answer 1

Using the probability concept, it is found that there is a $\frac{1}{4}$ probability that a teenager selected at random is female and their favorite hobby is watching films.

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem:

• Of those, 8 are female with a favorite hobby of watching films.

Hence:

$p = \frac{8}{32} = \frac{1}{4}$
