Answer:

0.017

Step-by-step explanation:

The probability that each of the firms called is owned by a woman is 0.36. Therefore, the probability that ALL four of the firms called are owned by women is:

[tex]P(W=4) = 0.36*0.36*0.36*0.36\\P(W=4) = 0.01679[/tex]

Rounding to three decimal places, the probability that all four are owned by women is  0.017
