6 of 10 1.2 Probabilities of a single trial Total Area = 1 P ( A ) P ( B ) P ( A or B ) Total Area = 1 P ( A ) P ( B ) P ( A or B ) = P ( A ) + P ( B ) - P ( A and B ) When events are not disjoint, we must subtract P ( A and B ) to only count the overlapped area once. Determine if the following events are disjoint for a single trial: Question 8 . (A) Being Female, (B) Running for President Question 9 . (A) Watching the PBS 6pm news program, (B) Watching the FOX 6pm news program. Easy method for addition rule P ( A or B ) = number of ways A + B occur total number of ways in S.S. (4) Never double count and this simple method works!!! R: table ( gender , t r a n s p o r t a t i o n ) t r a n s p o r t a t i o n gender CAR PUBLIC TRUCK FEMALE 9 1 1 MALE 4 1 2 Find the probability of randomly selecting (using our class data above): Question 10 . A student that drives a car. Question 11 . A female student. Question 12 . A female student that drives a car. Question 13 . A female student or a student who drives a car.
