the only possible option is 4 blrs, 1wk and 6 batsmen if i understand the q correctly. This can be done in 6C4x4C1x11C6 =15x4x462=27720 ways

if you want to include majority batsman and atleast 4 bowlers then

it can be 4bolwers, 6 batters 1wk
= 6C4*11C5*4C1 =15*462*4 = 27720

Yes ans = 27720.

1 wicket keeper can be selected in C(4,1) ways
4 bowlres chosen = C(6,4)
Remaining 6 batsmen = C(11,6)

Total possibilities = C(4,1) * C(6,4) * C(11,6) = 27720.

The batsmen has to be majority. So the split cannot be 1WC, 5Bowlers, 5Batsmen.
It can only be 1WC, 4bowlers and 6batsmen.
