5c3*11c3+5c4*11c2+5c5*11c1 - 10 years agoHelpfull: Yes(24) No(0)
- (5c3*11c3)+(5c4*11c2)+(5c5*11c1)
1936 - 10 years agoHelpfull: Yes(8) No(0)
- 5c3*11c3+5c4*11c2+5c5*11c1=1936
- 10 years agoHelpfull: Yes(1) No(0)
- 5men 11women
5c3 11c3
5c4 11c2
5c5 11c1
so 5c3*11c3+5c4*11c2+5c5*11c1=1936 - 10 years agoHelpfull: Yes(1) No(0)
- total=6 men(5) women(11)
3 3
4 2
5 1
no of ways=(5c3*11c3)+(5c4*11c2)+(5c5*11c1)=1936 - 10 years agoHelpfull: Yes(1) No(0)
- sample space S=16C6
selecting atleast 3 men N=(5c3*11c2)+(5c4*11c1)+(5c5)
so,the number of ways=N/S - 10 years agoHelpfull: Yes(0) No(0)
- sorry...
((11c3*5c3)+(11c2*5c4)+(11c1*5c5))/16c6 - 10 years agoHelpfull: Yes(0) No(0)
- 5+11=16 getting 6 from 16= 16C6=8008
3 are from women 11C3 and remaining from men 5C3 ...11c3*5c3=1650
the probability..... 1650/8008 =75/364 - 10 years agoHelpfull: Yes(0) No(0)
