Roll two dices
Step-by-step explanation:
Every dice rolled has two chances of six of winning by showing a 1 or 2, which is the same as one chance of three.
On the opposite, you have four chances of six of loosing by getting a 3,4,5 or 6, which is the same as two chances of three.
Since the chances of loosing are bigger than the ones of winning, every roll makes it more probable of getting a 3,4,5 or 6, so you need to roll as few dices as possible, in this case two is the minimum allowed.
