Isabella's dad pays her a $20 'allowance' each week for chores she does around the house. This month her dad has come up with (what he believes) is a clever idea. Instead of paying Isabella$20, he will present her with two paper bags. Inside the frst bag are two $5 bills, and one $10 bill. Inside the second bag is one $5 bill, one $10 bill, and one $20 bill. Isabella gets to draw one bill from each bag and the resulting amount will be her allowance for the week. 1. What is the probability that Isabella will get a total that is less than $20 for her allowance? 2. In the long run, what should isabella expect her average weekly allowance to be with her dad's proposal? Should she take her dad's offer? Explain your reasoning.
