      Some Simple Counting Rules EE304 - Probability and Statistics Semester 1 Some Simple Counting Rules. Counting If all outcomes are equally likely, the probability of an event E is given by jEj jSj where jEj(jSj) denotes the number of elements in E (S). To apply this rule, we need to be able to count the number of

      2. What is the probability that the outcome will be "3-C?" SOLUTIONS 1. There are six equally likely outcomes when we roll the die. There are four equally likely outcomes when we roll the die. According to the Fundamental Counting Principle, if we spin the spinner and roll the die the number of outcomes is (6)(4) = 24 2.

      A Guide to Counting and Probability Teaching Approach The videos in this whole series must be watched in order, and it would be good to first watch all the Grade 10 and Grade 11 videos on probability before these videos are watched as the concepts on probability need to be formed already before this series can be used.

      34 Probability and Counting Techniques If you recall that the classical probability of an event E ⊆ S is given by P(E) = n(E) n(S) where n(E) and n(S) denote the number of elements of E and S respectively. Thus, finding P(E) requires counting the elements of the sample space S. Sometimes the sample space is so large that shortcuts are needed ...

      other. (Note the similarity with the product rule used for counting.) For example suppose we want to compute the probability of rolling a die twice and getting a 6 each time. The outcome of the rst roll has no e ect on the outcome of the second roll. Therefore the two rolls are independent. The probability of getting a 6 on each roll is 1/6 ...
