Step 1: Recall the definition of the probability  

          DEFINITION: The relative possibility that an event will occur, as expressed

           by the ratio of the number of trials in which the event happened to the  

          total number of trials


           The experimental or empirical probability P(E) of an event E is

                      P(E)=\frac{Number\ of\ trials\ inwhich\ the\ event\ happened}{Total\ number\ of\ trials}


  • Probability is a branch of mathematics that deals with calculating the likelihood of a given event's occurrence, which is expressed as a number between 1 and 0. An event with a probability of 1 can be considered a certainty

            EXAMPLE: We know that a die has a total of 6 possible outcomes. You can

            roll a 1, 2, 3, 4, 5, or 6. Next, we need to know how many choices we have.

            Whenever you roll, you will get one of the numbers. You can't roll and get

            two different numbers with one die. So, our number of choices is 1. Using

            our formula for probability, we get a probability of \frac{1}{6}.
