Randomly selecting four person committee consisting entirely of women from a pool of 12 men and 15 women. the event of selecting a woman and the event of selecting a woman the next time are independent or dependent? probability of randomly selecting four person committee consisting entirely of women from a pool of 12 men and 15 women is

We are asked if the event of selecting a woman and the event of selecting a woman the next time are independent or dependent.

We can see that events are dependent because if one woman is already picked in the first draw....the probability of choosing a woman in the second draw will be different because number of woman is reduced.

The probability of randomly selecting four person committee consisting entirely of women from a pool of 12 men and 15 women will be

Therefore, probability of randomly selecting four person committee consisting entirely of women from a pool of 12 men and 15 women is 0.0777.

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
