Re: [OT] Math

OK, now hold yer horses:

I want to know the equation for finding the answer to the original 
question: what is the probability of either exactly four, or four or 
more, hits given each shot has a 1 in 6 chance of hitting.

I don't want the answer; I want the general equation from which the 
answer is derived.

If an explanation would take some great length, then feel free to 
contact me off-list.

Thanx,
