Answer 2

Given :

Total students : n = 8

no. of boys : b = 3

no. of girls : g = 5

To find :

2 boys must be selected in 4 students team.

Step-by-step explanation:

combinations of selecting 2 boys from 3 boys :

$_{3} C_{2}$   = 3

combinations of selecting 2 girls from 5 girls :

$_{5} C_{2}$ = 10

combinations of selecting 4 students from 8 :

$_{8} C_{4}$ = 70

Probability that 2 boys are selected = $\frac{3 *10}{70}$

                                                            = 3/7

Hence , the correct answer is 3/7
