Question

team of five is to be selected from 8 boys and 3 girls find the probability that it include two particular girls​

Answer 1

Given:

Total number of boys = 8

Total number of girls = 3

To Find:

That the team includes at least two particular girls

Solution:

Total number of people = 11

Team to be formed from = 5

Therefore = 11C5

Number of ways to select two particular girls = 2C2

Number of ways to select three members from everyone =  8+3−2

11 -2

= 9

Therefore, the probability will be -

= 2C2 x 9C3 / 11C5

= 84/ 462

= 42/231

Answer: The probability that it includes two particular girls is 42/231.
