165
155
135
Explanation
1 Captain, 1 vice-captain are already present
$\Rightarrow$ We need to select 8 players such that atleast 3 batsman and bowler must be there
Batsman | Bowler | Number of ways |
---|---|---|
3 | 5 | ${ }^6 C_3 \cdot{ }^5 C_5=20$ |
4 | 4 | ${ }^6 C_4 \cdot{ }^5 C_4=75$ |
5 | 3 | ${ }^6 C_5 \cdot{ }^5 C_3=60$ |
Total = 155 ways
