Answer 1

Answer:

If 3 female prison inmates  are selected at random,  the probability that none

are mothers = $\frac{1}{64}$

Step-by-step explanation:

Let the total number of prison inmates be 100

Given that Seventy-five percent of female  prison inmates are mothers.

The number of mother inmates = 75% (100) = 75

The number of inmates who are not mothers = 100 - 75 = 25

3 female prison inmates are selected at random. The probability that none  are mothers = ??

Selecting an inmate who is not a mother = $\frac{25}{100}$ = $\frac{1}{4}$

Selecting 3 female who are not mothers = $(\frac{1}{4} ) (\frac{1}{4} ) (\frac{1}{4} )$ = $\frac{1}{64}$
