Short Answer

SCENARIO 4-17

can either take the shuttle bus which is usually running late 20% of the time or ride his unreliable
motorcycle which breaks down 40% of the time. He decides to toss a fair coin to make his choice.
-Referring to Scenario 4-17, if Jake is late to the test, what is the probability that he took the bus?
