If by 4 you mean either 3+1 or 2+2, then: (1/12)4(11/12)(5) = 55/(125) = 0.00022103
Suppose A is the event {rolling a 6-sided die 20 times and getting a 5} Then A', the complement of A, is the event {rolling a 6-sided die 20 times and not getting a 5 any times} So Pr(A) = 1 - Pr(A') = 1 - (5/6)20 = 1 - 0.026084 = 0.973916 (to 6 dp)
1 in 6 times 1 in 6 equals 1 in 36
1/6 times 1/6 times 1/6= 1/216 chance of getting a 4.
It is 0.1962
Theoretical probability is the probability of something occurring when the math is done out on paper or 'in theory' such as the chance of rolling a six sided dice and getting a 2 is 1/6. Experimental probability is what actually occurs during an experiment trying to determine the probability of something. If a six sided dice is rolled ten times and the results are as follows 5,2,6,2,5,3,1,4,6,1 then the probability of rolling a 2 is 1/3. The law of large numbers states the more a probability experiment is preformed the closer to the theoretical probability the results will be.

The probability of rolling at least one 2 when rolling a die 12 times is about 0.8878. Simply raise the probability of not rolling a 2 (5 in 6, or about 0.8333) to the 12th power, getting about 0.1122, and subtract from 1.
The probability is (0.1) times (the number of faces with '4' marked on them).

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.
The probability of rolling a 3 with a standard die is 1 in 6. The probability of doing that two times in a row is 1 in 6 squared, or 1 in 36.
It is 0.99999406 approx, or pretty nearly a certainty.
