If rolling 1 die it is 1; if rolling 7 dice it is 0.
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.
The probability is 7/36
It is 0.
What do you think? Its a tiny bit very obvious.
The probability of rolling a 7 on a standard die is 0. It will not ever happen.
The probability is 1/6.
The probability of rolling a 7 at any time on a single die is zero.
If rolling 1 die it is 1; if rolling 7 dice it is 0.
The probability of rolling a 7 with 2 dice is 6/36; probability of rolling an 11 is 2/36. Add the two together to find probability of rolling a 7 or 11 which is 8/36 or 2/9.
With a single throw of a normal die, the probability is 0.With a single throw of a normal die, the probability is 0.With a single throw of a normal die, the probability is 0.With a single throw of a normal die, the probability is 0.

The probability is 1/42.
The probability is 7/36
It is 0.

Probability of rolling a 3 is 2/36 & the probability of rolling a 6 is 5/36; probability of rolling a 3 or 5 is 2/36 + 5/36 = 7/36.
