Question

A classroom has 11 boys and 14 girls.

If 3 random students are selected, what is the probability that there will be 2 boys?

Answer 1

None

Explanation:

Let S be the sample space and E be the event of selecting 1 girl and 2 boys.Then, (S) = Number ways of selecting 3 students out of 25C3=2300

n(E) = (11C1×14C2)= 1001 P(E) = 1001/2300
