Solution: We have to find the probability of randomly selecting four person committee consisting entirely of women from a pool of 12 men and 15 women.
The number of ways 4 women can be selected from 15 women is:
15C4

The number of ways 4 persons can be selected from total 12+15 = 27 persons is:
27C4

Therefore, the probability of randomly selecting four person committee consisting entirely of women from a pool of 12 men and 15 women is:

The event of selecting a woman and the event of selecting a woman the next time are dependent because the probability of selecting a woman at first draw is not same as the probability of selecting a woman at second draw.
Answer:
(a) 113.04m²
(b) 37.68m
Step-by-step explanation:
(a)
Area = πr²
=π(6)²
=36π
=113.04m²
(b)
Circumference = 2πr
2π(6) = 12π
=37.68m
Answer:
It may be 71.78 cm square
