Answer:
Mean = 1.57
Variance=0.31
Step-by-step explanation:
To calculate the mean and the variance of the number of successful surgeries (X), we first have to enumerate the possible outcomes:
1) Both surgeries are successful (X=2).

2) Left knee unsuccessful and right knee successful (X=1).

3) Right knee unsuccessful and left knee successful (X=1).

4) Both surgeries are unsuccessful (X=0).

Then, the mean can be calculated as the expected value:

The variance can be calculated as:

2- 12.5%
The hours between 12-8 is a total of 8 hours
6 to 8 is a total of 2 hours
2/8 is 25 percent but there are two days on the weekend so therefore it’s a 50 50 Chance to play on Sunday so divide 25 in half and you get 12.5 %
