could some of you help me to find out what is the probability of A) obtain with two dice a greather number than another die?
B) and if the dice are 3 how can I do?
Not the sum of the 2 dice, but the greatest value of those 2 against another die

If $X$ is the sum of the two dice, and $Y$ the value of the one die, then
what are the possible outcomes $(x,y)$ and which one are "winning"? Then compute their probabilities by independence and add.



Or compute when the one die wins :



$P(Y=6)P(X le 5) + P(Y=5)P(X le 4) + P(Y=4)P(X le 3) + P(Y=3)P(X le 2)$



which equals $frac{1}{6}(frac{1}{36} + frac{3}{36} + frac{6}{36} + frac{10}{36})$



and take the complement of that.
