​
-
Let the three rolls be rearranged in nondecreasing order: a < b < c. Then the median is b. Translate “mean equals median” into the equation (a+b+c)/3 = b.
-
Interpret the condition the problem gives: it forces a, b, c to be in arithmetic progression (equally spaced). Now count how many suchtriples can happen with values 1 through 6, and remember to convert from sorted triples to ordered dice outcomes.
