a. Use the inclusion/exclusion principle.
b. By definition of conditional probability,
80=-8a
We are trying to solve for a. So we need to get a alone. To do that we have to divide each side by -8.
80/-8= -8a/-8
Once you have solved each side you will get the following.
-10=a
Expanded: 3x^2 + 17x +10
Simply: it’s already simplified
