Question

in a survey of 350 women 132 were found to be working if a woman is selected at random find the probability that she is not working

Answer 1

not working women's are 350-132 = 218
so probability is 218 /350 or 109 /175

Answer 2

Given:

Total number of women in survey=350

Total number of working women in survey=132

To find:

The probability of non-working women in the survey

Solution:

The probability of non-working women in the survey is 109/175.

We can find the probability by following the given process-

We know that the number of women not working can be obtained s the difference between the total number of women and the number of working women.

The number of women not working=Total number of women in the survey-Number of women working

=350-132

=218

The probability of non-working women in the survey=Total number of non-working women/ Total number of women in the survey

On putting the values, we get

=218/350

=109/175

Therefore, the probability of non-working women in the survey is 109/175.
