MATH 399N Week 3 Discussion: Probability and Odds

Professor and Class,

Classical probability is used when each outcome in a sample space is equally likely to occur. The classical probability for an event E is given by P(E) = the number of outcome in an event E / total number of outcome in a sample space.

(1) Find the probability of each even from rolling a 12-sided die

(a) Event: rolling a 2 (b) Event: rolling a number greater than 4 (c) Event: rolling a number divisible by 5

Event A – Rolling a 2. A = 2 so P = 0.83

Event B – Rolling a number > 4 . B = 12 so P = 0.667

Event C – Rolling a number divisible by 5. C = 4 so P = 0.333variable
