The correct question is:
What is the probability that 2 girls and 2 boys will be selected?
Solution:
Total number of students = 10
Ways to select a team of 4 students = 10C4 = 210
2 Boys can be selected from 6 boys in ways = 6C2 = 15
2 Girls can be selected from 4 girls in ways = 4C2 = 6
Number of ways to select 2 boys and 2 girls = 15 x 6 = 90
Probability of choosing 2 boys and 2 girls = 90/210 = 3/7
Thus, if 4 team members are selected, the probability of choosing 2 boys and 2 girls will be 3/7
