Combinations Probability Q... (1 Viewer)

[tempco]

If a question is something like this:

7 men, 4 women.

A committee of 5 people must be chosen.

The restriction is that the majority of the committee must be women... so would the answer incorporate the committee having no men and 5 women? or must there be at least 1 man in the committee?

EDIT: Duh. 5 women committee is impossible... >_<

 

[ToO LaZy ^*]

that question looks very similar to the one i just did..
so yes, you should include 0 men and 5 women

 

[tempco]

That's only if there are 5 women in the first place right

5 women from a selection of 4 women? lol. one of the men had a sex change?

possibilities:
(4W, 1M) + (3W, 2M) = 4c4.7c1 + 4c3.7c2 = 91
