There are 4 bowlers in 13 player team.
So, maximum we can add 4 bowlers.
And we need to include at least 3 bowlers.
If we include 3 bowlers then from the remaining 9 [13 – 4 bowlers] players, we need to include 8.
The number of ways, 8 players can be selected among 9 is = 9C8 = 9 The number of ways,
3 players can be selected among 4 is = 4C3 = 4
So, taking 3 bowlers the team can be represented in (9 X 4) = 36 ways.
If we include 4 bowlers then from the remaining 9 [13 – 4 bowlers] players, we need to include 7.
The number of ways, 7 players can be selected among 9 is = 9C7 = 36
The number of ways, 4 players can be selected among 4 is = 4C4 = 1
So, taking 4 bowlers the team can be represented in (36 X 1) = 36 ways.
Therefore, the total possible ways are = (36 + 36) = 72.
