### What are the formulas for Theoretical Probability?

There are no generic answers. The theoretical probability for
rolling a die and tossing a coin will, obviously, be different. The
theoretical probability of an event is calculated by finding a
suitable model for the trial and then using scientific laws to
determine the probabilities of its outcomes.

### What is the theoretical probability of rolling a factor of 6 on a die rolls 100 times?

The theoretical probability of rolling something other than a
factor of 6 in one roll is 2/6 or 1/3.
So, the probability of rolling something other than a factor of
6 in 100 rolls is (1/3)^100 = 1.94*10-48
And therefore.the probability of rolling a factor of 6 is 1 -
Prob(not a factor)
= 1 - 1.94*10-48 which is incredibly close to 1.

### What would be the theoretical probability of rolling a die 50 times and rolling a 2?

The probability of rolling at least one 2 in fifty rolls of a
standard die is 1 - (5/6) 50, or about 0.99989012.
This calculation starts by looking at the probability of not
rolling a 2, which is 5/6. To repeat that 50 times in a row, you
simply raise that to the 50th power, getting 0.000109885. Then you
subtract the result from 1 to get the probability of not succeeding
in not rolling a 2 in fifty tries.
Expressed in normal "odds" notation, this is about (100000 - 11)
in 100000, or about 99989 in 100000.
