11-60.

You roll three different-colored dice and use the numbers on the dice to determine the lengths of the sides of a triangle. For example, $3\text{-}3\text{-}5$ would be an isosceles triangle with base $5$. What is the probability of building a right triangle?

Can you use combinations if each combination is not equally likely?

How many special right triangles have leg lengths under $6$?

$\frac{3\cdot2\cdot1}{6\cdot6\cdot6}$
