The prob of rolling a 4 is (1/6) the prob of rolling 2 is simply
(1/6)(1/6) = (1/36) or 0.028

The probability of rolling 4 on the first roll is 1 out of 6. The probability is the same on the second roll. To determine the probability of rolling 4's on both rolls, you multiply those together:
1 out of 36.

^
the probability of rolling a 4 once is (1/6).
the probability of rolling two 4's is
(1/6)(1/6) = (1/36)

Probability of any 1 particular "double" is 1/36
Probability of rolling a double is 1/6

If ALL FOURS means you roll four both times, the probability is 1 thirty sixth
