Tasya [4]

Answer:

Step-by-step explanation:

Given -

A business organization needs to make up a 8 member fund-raising committee.

The organization has 6 accounting majors and 6 finance majors .

Total no of ways can the fund raising committee be formed if at least 4 accounting majors are on the committee.

(1) chose 4 accounting majors from 6 and chose 4 finance majors from 6 =

= $\binom{6}{4}\times\binom{6}{4}$

= $\frac{(6!)}{(2!)(4!)}\times \frac{(6!)}{(2!)(4!)}$ = 225

(2) chose 5 accounting majors from 6 and chose 3 finance majors from 6 = $\binom{6}{5}\times\binom{6}{3}$

= $\frac{(6!)}{(1!)(5!)}\times\frac{(6!)}{(3!)(3!)}$ = 120

=

(3) chose 6 accounting majors from 6 and chose 2 finance majors from 6 = $\binom{6}{6}\times \binom{6}{2}$

= $\frac{(6!)}{(6!)(0!)}\times\frac{(6!)}{(2!)(4!)}$ = 15

Then total no of ways = (1) + (2) + 3

= 360

= 35 - 10

= 25 boys

Probability that the winner is a boy is:

= 25/35

Take that fraction to the simplest by dividing both by 5:

= 5/7
