Suppose that 52% of the people have been vaccinated. If 25 people are randomly selected, answer the following questions.

(a) [1] What is the probability that exactly 12 of them have been vaccinated?

(b) [2] What is the probability that at least 10 of them have been vaccinated?

(c) [2] Determine the probability that between 11 and 15 (including 11 and 15) of them have been vaccinated.

(d) [2] What is the expected number of of them have been vaccinated and its standard deviation?
