Answer:
There are 15 players for selection. Lets assume that all players are allrounders. player A is always selected, therefore there will be only 10 players to be selected. Again one particular player B cant be selected, so there are 13 players from which you are gonna select 10 players.
So according to permutation and combination theorems that will be 13 C 10 i. e fact(13)/(fact(10)*fact(3))= 286 ways.
But if you consider real scenario:
There will be 3 opening batsmen.
There will be 5 batsmen in which two are wicket keeper.
2 All-rounders(one fast bowling and another spin bowling)
4 fast bowlers
One spinner
So in the above mentioned scenario, spinner is selected who is player A in above mentioned para. So, now according to pitches one all-rounder will be selected. And from 4 fast bowlers, 3 will be selected. From 3 opening batsmen, 2 will be selected. In 5 batsmen one keper batsmen is eliminated, who is player B.
So, no. of ways will be
3C2*4C4*2C1*4C3= 24 ways
