A survey has a success rate of 75%. Suppose that the surgery is performed on three patients.

1. What is the probability that the survey is successeful on at least 2 patients?

2. On average, how many surgeries can we expect of successful if performed on a group of three patients?

3. What is the standard deviation of the number of succeful surgeries performed on a group of three patients?
