Because 3/6 of the sides on a number cube have even numbers, the probability of rolling even on one number cube is 1/2(equivalent of 3/6). But since you're rolling twice, you multiply the probability of one by itself (therefore rolling 2 number cubes). So:
1/2x1/2=1/4
The probability of rolling an even number when a number cube is rolled twice is 1/4, 25%, or 1 out of 4.

When a number cube is rolled twice, there are 36 possible outcomes. (1,1),(1,2),....(6,6). (3,3) occurs only once. Therefore, the probability of rolling a 3 both times is 1/36.

The probability of rolling 7 once with two dice is 1 in 6, o 0.1667. The probability, then, of doing that twice in a row is 1 in 36, or 0.02778.
Since you need a specific number - the number 6 - twice, the probability is (1/6)2, which is equal to 1/36.Since you need a specific number - the number 6 - twice, the probability is (1/6)2, which is equal to 1/36.Since you need a specific number - the number 6 - twice, the probability is (1/6)2, which is equal to 1/36.Since you need a specific number - the number 6 - twice, the probability is (1/6)2, which is equal to 1/36.
Let A be the event of rolling a 4. P(A) = 1/6 P(A)P(A)=(1/6)(1/6)=1/36 Therefore, the probability of rolling a 4 twice with two rolls of a number cube is 1/36.
