Answer:

Step-by-step explanation:

a) 0.125, b) 0.1124, c) 0.505

Step-by-step explanation:

Since we have given that

Number of boys in 10A = 30

Number of girls in 10A = 20

Number of boys in 10B = 15

Number of girls in 10B = 25

So, we need to select one student from each class.

So, a) what is the probability of both being girls?

b) what is the probability of both being boys?

c) what is the probability of one boy and one girls?

Hence, a) 0.125, b) 0.1124, c) 0.505.
