Welcome to the forum. Have you heard of the binomial distribution?

How many ways can this be done? I presume this implies Combination WITHOUT repetition, and if so I got 210. The formula I used was n!/k!(n-k)! Thus, 10*9*8*7/4*3*2 = 210 Now a follow up question is: If there are 5 men and 5 women, what is the probability there would be at least 1 woman? \How do I do this? What formula do I use?]]>http://www.mathisfunforum.com/profile.php?id=2168632017-10-09T12:45:50Zhttp://www.mathisfunforum.com/viewtopic.php?pid=400981#p400981
