The parents could have 3 boys and 3 girls in 400 ways
<h3>How to determine the number of ways?</h3>The given parameters are
Children, n = 6
Boys, r = 3
Girls, r =3
The number of combination is:
So, we have:
Apply the combination formula
This gives
Ways = 400
Hence, the parents could have 3 boys and 3 girls in 400 ways
