The probability is 11/36. There are 36 possible outcomes, but 25 of these don't involve a 2 on either die.

The way to answer this is to ask what is the probability of not rolling a 2 on either die and subtract this from one.

The probability of not rolling a 2 with the first die is 5/6. It is of course also 5/6 chance of not rolling a 2 with the second die. So we multiply the probabilities and subtract from 1.

1 - (5/6 * 5/6) = 1 - (25/36) = 11/36.

Probability is desired options over total options. There are 6 faces on a standard dice, so NOT rolling a 5 is 5/6.

What is the theoretical probability of rolling a 5 on a number cube if it is rolled 300 times?

The theoretical probability of rolling a 5 on a standard six sided die is one in six. It does not matter how many times you roll it, however, if you roll it 300 times, the theoretical probability is that you would roll a 5 fifty times.

What is the probability of rolling an even number on a standard 6 sided die if an even number is rolled 7 times out of 12?

A standard die has no memory and so the probability of rolling an even number is always a half. If you did not know that the die was standard and were using the fact that 7 out of 12 rolls were even as an empirical estimate for a loaded die then the answer is 7/12.
