Two questions
1. A football match may be either won, drawn, or lost, so there are three ways of forecasting the result of any one match, one correct and two wrong. Find the probability of forecasting at least three correct results.

I have no idea how to begin this other than that $\displaystyle P(C)=\frac{1}{3}$ and $\displaystyle P(I)=\frac{2}{3}$

2. Three unbiased dice numbered 1,1,2,2,3,3 are tossed. Find the probability of throwing either ate least one 2 or at least one 3.

I'm lost on this one as well.
Thanks

That's the whole question, no mention about how many games played.
