Demographics and Population Statistics
Most physicians in Canada graduated from a medical school in Canada. However, some attended medical school in the United States or another foreign country. The probability that a physician in Alberta attended a Canadian medical school is 0.684; in British Columbia, 0.705; in Quebec, 0.891; and in Ontario, 0.736.8 Suppose one physician is independently selected from each province, and let the random variable Y be the number of physicians who attended a Canadian medical school.
a. Construct a probability distribution for Y.
b. What is the probability that at least one physician attended a Canadian medical school?
c. Suppose another group of physicians is selected, one from each province. What is the probability that at least three physicians from each group attended a Canadian medical school?
