A cricket team of 11 players is to be chosen from 16 players which includes 5 bowlers and 2 wicket keepers. How many ways can a team be selected if each team must have 3 bowlers and 1 wicket keeper?? Plzzz answer!!

we are to choose 11 players , including at least 3 bowlers and 1 wicket keeper.
out of 16 players , number of bowlers = 5 and the number of wicket keepers = 2
others = 16-(5+2)=9
now the required selection can be done in following manner:
$$\begin{gathered} \underset{\left(i\right) case}{3 B +1W+7Ot} or \underset{\left(ii\right) case}{3B+2W+6Ot} or \underset{\left(iii\right) case}{4B+1W+6Ot} or \underset{\left(iv\right) case}{4B+2W+5Ot} \\ or \underset{\left(v\right) case}{5B+1W+5Ot} or \underset{\left(vi\right) case}{5B+2W+4Ot} \end{gathered}$$
$$\begin{gathered} ={}^{5}C_3.{}^{2}C_1.{}^{9}C_7+ {}^{5}C_3.{}^{2}C_2.{}^{9}C_6+ {}^{5}C_4.{}^{2}C_1.{}^{9}C_6+ \\ {}^{5}C_4.{}^{2}C_2.{}^{9}C_5+ {}^{5}C_5.{}^{2}C_1.{}^{9}C_5 + {}^{5}C_5.{}^{2}C_2.{}^{9}C_4 \\ =10*2*36 +10*1*84 + 5*2*84 + 5*1*126 +1*2*126 +1*1*126 \\ =720+840+840+8*126 \\ =2400+1008 \\ =3408 \end{gathered}$$

hope this helps you
