Tips and Tricks on Probability


 


1
When you roll a die, the possible outcomes are 1, 2, 3, 4, 5 and 6 -- so the sample space is {1,2,3,4,5,6}.



2
If we roll a pair of dice (and we can tell the dice apart) then the sample space has 36 outcomes, and each is equally likely, and so has a probability of 1/36.

Probability of occurrence and Event Probability of any Event P = n (E) / n (S) P (E) = Probability of Event n (E) = Total number of required outcomes n (S) = Total number of Possible outcomes
