In a school 4 5 of the children are boys and the number of girls is 100 find the number of boys?

4/5 of the children are boys.
So 1 - 4/5 ie 1/5 of the children are girls.
1/5 = 100 so 1 = 500 ie there are 500 children in all.
4/5 of 500 is 500*4/5 = 400
So there are 400 boys.

What is the probability of having exactly 2 boys out of 6 children?
The answer depends on whether the children are picked at random. If they were selected from inside a girls' school the probability should be quite close to 0.
