Probability (Exam Notes)

Always remember that probability = Favourable outcomes
                                                             Possible outcomes
Experimental probability- actually doing the trials.
Theoretical probability- what you expect to happen.


Eg.

P (heads and rolling a 4 with a regular die)

Since there is 12 possible outcomes the experimental probability is 1 or 1:12 or 0.83%
                                                                                                           12
