Given that,
We need to select 11 players out of available 17 players in which 5 players are bowlers.
It is also mentioned that each team should contain exactly 4 bowlers.
Let us assume the no. of ways of selection be N.
⇒ N = (no. of ways of selecting 4 bowlers out of 5) × (no. of ways of selecting 7 players from remaining 12 players)
⇒ N = (5C4) × (12C7)
We know that,
nCr = \(\frac{n!}{(n-r)!r!}\)
And also,
n! = (n)(n – 1)......2.1
⇒ N = 5 × 792
⇒ N = 3960
