Suppose a new surgical intern operates on eight patients using a procedure that has a current estimated success rate of 76%. The following table illustrates the total number of possible successes for the intern and their corresponding probabilities:

Probability	Number of Successes
0	1	2	3	4	5	6	7	8
0.001	0.011	0.072	0.103	0.127	0.173	0.278	0.146	0.080

1. What is the expected number of successful operations for the surgical intern?
2. What is the variance of the distribution?
