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 either Simon, Paula, or both of them trying to rescue the man?

Question

Quizplus · Accepted Answer

To find the probability of either Simon, Paula, or both trying to rescue the man, we can calculate the probability of neither of them trying to rescue the man and subtract it from 1. The probability of neither trying is 0.3 (30% chance Simon doesn't try) * 0.3 (30% chance Paula doesn't try) = 0.09 or 9%. Therefore, the probability of either or both trying is 1 - 0.09 = 0.91 or 91%.
