The sample space for tossing a coin twice is [HH, HT, TH, TT].
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.

The chance of rolling a 6 twice in a row, on a six-sided die, is 1 in 36 or 2.78%. The number of possible different results for rolling a six-sided die twice is 6 squared (6 times 6), or 36, therefore the probability of getting any one of the possible results is 1 out of 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.

It is 1/36.
The chance of rolling a 6 twice in a row, on a six-sided die, is 1 in 36 or 2.78%. The number of possible different results for rolling a six-sided die twice is 6 squared (6 times 6), or 36, therefore the probability of getting any one of the possible results is 1 out of 36.
In 2 rolls, it's 1/6 = 162/3% if you don't care what the number is.If you name the number you want before rolling, it's 1/36 = 27/9%.
That depends on whether you roll it twice or not...

If it is a regular dice then the probability is 3/6 that is 1/2
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.
