Combination

[sensational]

My name is Binoka and I am a senior in High School, I know that in mathematics, the order doesn't matter in combination.

The question is: Election is to be held for the school committee. Six students are to be elected. The canditates are six female students and seven male students.
How many committees with at least one female is it possible to choose?

Please prove me if I'm wrong

we use the formula,

n= 13, r= 6? because of the six students to be elected

when we calculate in the formula we get we get 1716

How many ways can you choose 6 male students out of total 7 male students?

Those will be the committees with only male students.

Those need to be discarded from the total number you have calculated before (since every committee must have at least one female member)

Thanks Subhotosh Khan for your time helping me.
Now I understand this question
so you just minus 1716 with the committees with only male that is 6
=1710

Thank you again Khan.
