Answer 2

The probability that she is not a working woman is 0.299 or $\frac{83}{278}$.

Step-by-step explanation:

Consider the provided information.

in a survey of 278 woman 195 were found to be working.

That means the number of woman who are not working is:

278-195=83

We need to find the probability that if a woman is selected she is not a working woman.

$Probability = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$

$Probability = \frac{83}{278}$

$Probability \approx 0.299$

Hence, the probability that she is not a working woman is 0.299 or $\frac{83}{278}$.
