One way is to first count the number of outcomes in the particular situation or experiment. Call this number N.
Then if you are asked what is the probability of some event A. Assuming all outcomes are equally likely. count the number of outcomes that make event A true. Call this number x.. Then the Probability of A = Pr ( A) =
x / N
