Mech_Engineer, that's simply not true. Without doubt, there are many fraudulent people out there claiming to have psychic abilities and to "speak to the dead." But everyone cannot be simplistically grouped under that designation. I'm okay with the idea that there is no afterlife, but there are...

Thank you again, Mattmns. That really helped alot. The answer is definitely 6. But I wasn't able to come up with the answer by figuring it out mathematically (e.g. by applying a formula), I had to draw a picture on a piece of paper. Do you know of any way to figure the problem out purely...

Thank you for your response! It took a while, but with your hint, I did eventually get it. Here is what I did: a) C(11,6) - C(9,5) = 336 b) C(6,3) x [C(5,4) - C(3,2)] = 40 Thanks again. :-) BTW, this is another probability problem that, for some reason, I am really hung up on. Can anyone...
