Looking for help with java probability assignment.

I'll use pastie to show the assignment for clarity. I can't find the correct equation to even find the probability in the first place, nevermind writing the rest of the program.. Any advice or partial code will help!

Thanks.

Please post the assignment verbatim in the forum, not in a link. Please show what you've tried. Anything, so long as you've tried.

I figured it out, close/lock. Thanks.
