Answer 1

Answer:

Chemistry = 4 Girls, 8 Boys, and 12 students in total

Physics = 6 Girls, 4 Boys, and 10 students in total

Bio = 6 Girls, 4 Boys, and 10 students in total

Step-by-step explanation:

First, find out the no. of boys and girls

1/2 × 32 = Boys = 16 Boys

1/2 × 32 = Girls = 16 Girls

No. of boys enjoying physics = 4

Total students enjoying Physics = 5/16 × 32 = 5 × 2 = 10 Students

So, automatically,

No. of students enjoying physics = 4 Boys, 6 Girls

Probability of picking a random girl who enjoys Chemistry = 1/4 × 16 = 4 Girls

So,

No. of Girls enjoying Chemistry = 4

No. of students enjoying Chemistry = 6/16 × 32 = 6 × 2 = 12 Students

So, Automatically,

No. of students enjoying Chemistry = 4 Girls, 8 Boys

No. of students enjoying Biology = 5/16 × 32 = 5 × 2 = 10 Students

Since students can only choose 1 subject, there are 4 Boys and 6 Girls left after the distribution in Physics and Chemistry enjoyers.

So, automatically,

No. of students enjoying Biology = 6 Girls, 4 Boyes
