Probability
Roll two dice. In how many of the 36 equally likely outcomes does at least one die show a 6?
The trick
Counting "at least one 6" directly is awkward. Instead, flip it around – there are 5 × 5 = 25 outcomes with no six, so 36 − 25 = 11 have at least one. (Not 12 — that double-counts the double-six).
