Scenario 12.1 : Simon and Paula are walking home from school and come across a man being attacked by a crazed miniature poodle. It takes only one of them to save the man from the poodle, but since responsibility is diffuse, each is only 70% likely to try to rescue the man.
-Refer to Scenario 12.1. What is the probability of Simon trying to rescue the man and Paula not helping?

Question

Quizplus · Accepted Answer

The probability of Simon trying to rescue the man is 70% (or 0.7), and the probability of Paula not helping (assuming independence) is 30% (or 0.3, since if she is 70% likely to help, she is 30% likely not to help). Multiplying these probabilities gives 0.7 * 0.3 = 0.21, or 21%.
