- (5c0*11c11)+(5c1*11c10)+(5c2*11c9)+(5c3*11c8) =1650 + 550 + 55 +1 =2256
Hence 2256 is the answer. - 9 years agoHelpfull: Yes(4) No(0)
- given: team must comprise not more than 3men
so,
there can be possible choices of 3,2,1 or 0 men
correspondingly 8,9,10 o 11 women
to get a team comprising 11.
possible combinations are= (5c3*11c8) +(5c2*11c9)+(5c1*11c10)+(5c0*11c11)
on calculating: 1650+ 1550+55+1

- slect 0 men and 11 women + 1 men &10 women+2 men & 9 women +3men & 8 women.
so, 5c0*11c11+5c1*11c10 +5c2* 11c9 +5c3* 11c8 = 2256 ans - 9 years agoHelpfull: Yes(1) No(1)
- ans will be 2256

- Maximum 3 men can be played which means there can be 0, 1, 2, 3 men in the team.
(5C0×11C11)+(5C1×11C10) + (5C2×11C9)+(5C3×11C8) = 2256 - 9 years agoHelpfull: Yes(0) No(0)
- The Team may consist of 0 Man+ 11 Women ,1 Man+10 Women,2 Man+9 Women,3 Man+8 women
so 11c11+5c1*11c10+5c2*11c9+5c3*11c8=2256. - 9 years agoHelpfull: Yes(0) No(0)

- 5C0 * 11C11 + 5C1 * 11C10 +5C2 * 11C9 + 5C3 * 11C8 =2256

- Selecting 0 men and 11 women : 5c0+11c11
Selecting 1 men and 10 women : 5c1+11c10
Selecting 2 men and 9 women : 5c2+11c9
Selecting 3 men and 8 women : 5c3+11c8
Now it can't be 4 men and 7 women 5 men and 6 women because we have to choose men not more than 3.
possible combinations are= (5c0*11c11) + (5c1*11c10) +(5c3*11c8)+ (5c2*11c9)
on calculating: 1 + 55 + 550 + 1650
Ans: 2256 - 5 years agoHelpfull: Yes(0) No(0)
