Step-by-step explanation:

Answer 2

Answer:

The probability of selecting a woman is  $\frac{1}{14}$

Step-by-step explanation:

Total number of people = 70

Number of boys = 15

Number of girls = 20

Number of men = 30

Number of women = 70 - 15 - 20 - 30 = 5

We need to find the probability of the selected person being a woman.

We know that Probability = $\frac{FovaouableOutcomes}{TotalNo.Of Outcomes}$

Therefore, P(Woman) = $\frac{No. Of Women}{No. Of People}$

                                    = $\frac{5}{70}$

                                    = $\frac{1}{14}$

Therefore, the probability of selecting a woman is  $\frac{1}{14}$
