Answer 1

While rolling 2 dice, there are 36 equally-probable microstates: 1-1, 1-2, 1-3, up to 6-6. Six of those microstates are doubles. Therefore the probability of rolling doubles with two dice is 6 / 36 or 1 / 6.

Answer 2

IF ONE IS ROLLED AFTER ANOTHER:
The first die can land on anything so don't worry about it.
The second die has to land on the same number as the first die so the probability is 1/6

IF BOTH ARE ROLLED AT THE SAME TIME:
There are a total of 36 outcomes.
Six of those outcomes have the same number on both dice (1 and 1, 2 and 2, 3 and 3 etc.)
Probability is 6/36 or again 1/6

Answer 3

1' 1' 2 3 4 5 6
2' 1 2' 3 4 5 6
3' 1 2 3' 4 5 6
4' 1 2 3 4' 5 6
5' 1 2 3 4 5' 6
6' 1 2 3 4 5 6'

==> 6/36 => 1/6 <= Your Anwer :D

Answer 4

there are 6 faces on a standard die. the probability of any 1 side coming up is 1/6.

P(x) = 1/6

if he rolls another onethe chance of having the same # again is still 1/6, so you multiply the 2 probabilities

1/6 * 1/6 = 1/36

since there are 6 of these faces, add them up to get 6/36 or 1/6

Answer 5

i only roll a 20 sided die.
