A class has 20 students of which 12 are females and 8 are males. In how many ways can a committee of 5 students be picked from this class if no males are to be included in the committee?
So really the number of 8 male students is useless
12*11*10*9*8 = ? After every student is picked she cant be picked again. And there are 5 member is the committee.
So a female student cant be picked twice?
Pretty sure only 1 person can be running for a position.
hmmm
Well I think of it as there are 12 possible people to do this and only 5 to a group so I set it up as 12*5=
its 60 from what I am guessing
I get 94050
95040
No thats obviously too much xD
That is each possible combination that we can have. 60 is too little.
If there has to be atleast one different student in each group its 60 but if they have to be in different positions every time then you could do what I did with numbers 1, 2, 3, 4, 5 then 2, 1, 4, 5, 3 etc
But still we are talking about 12 girls maybe if we added them instead of multiplying
