The probability that Stu buys a sandwich is 0.5. The probability that Stu gets the bus is 0.7. Assuming the events are independent, what is the probability that Stu buys a sandwich and gets the bus?
First there is a 50% chance, or a 0.5 chance that Stu gets a sandwich. Then, ignoring the other .5, there is a .7 chance that he makes the bus. Thus, 1/2 of .7 is 0.35.
