**Re: Probability Again!**

1) The plural of "die" is "dice".

Pr(rolling a 6 with one die) = 1/6

Pr(rolling exactly one 6 with two dice) = PR(hitting the first and not the second) + Pr(Hitting the second and not the first) = (1/6)(5/6) + (5/6)(1/6) = 10/36

You can make a tree. There are several ways to go about getting all the way up to four dice.
