Default Re: Easy probability questions, plz answer ASAP

[ QUOTE ]
1) We have to choose a group of 5 people out ot 10(2 are married and 8 others). How many pictures are possible with 5 people if we have to include 1 person out of the married couple in the middle?(and we cant have them both in 1 picture).


[/ QUOTE ] 2*10!/6! assuming ordering matters

[ QUOTE ]
2)(Bridge) If we have a hand that consists of 13 cards, how many different hands can we have that contain exactly 3 suits ONLY.

[/ QUOTE ] 4*(39!/(26!*13!)) - 3*(26!/(13!*13!)) - 2 assuming you need EXACTLY three, and only the first term if you need three or fewer

This might be wrong. I did it in my head, so who knows?
