The board of directors of Saner Automatic Door Company consists of 12 members, 3 of whom are women. A new policy and procedures manual is to be written for the company. A committee of three is randomly selected from the board to do the writing. a) What is the probability that all members of the committee are men?b) What is the probability that at least 1 member of the committee is a woman?

(a) The probability that all members of the committee are men is 0.3818.

(b) The probability that at least 1 member of the committee is a woman is 0.6182.

Step-by-step explanation:

The number of men in the board of directors is 9.

The number of women in the board of directors is 3.

A committee of three is randomly selected from the board.

(a)

Compute the probability that all members of the committee are men as follows:

P (Selecting 3 men) = n (Selecting 3 men) ÷ n (Selecting 3 members)

Thus, the probability that all members of the committee are men is 0.3818.

(b)

Compute the probability that at least 1 member of the committee is a woman as follows:

P (At least 1 woman) = 1 - P (All 3 men)

Thus, the probability that at least 1 member of the committee is a woman is 0.6182.

its not b

step-by-step explanation:

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
