Brain Game: Wouldn't It Be Dice?

Today's Brain Game involves good, old-fashioned six-sided dice. If you roll a single die, you have the same chance of rolling a 1 as you do rolling a 2, 3, 4, 5, or 6. The numbers change with multiple dice, however, as we'll see. Good luck:

A friend bets you that he can roll a total of 10 with three dice
more often than you can roll a total of 8 with only two dice.

Do you take the bet?
