Amy is taking a statistics class and a biology class. Suppose her probabilities of getting a grade of A+ in statistics course is 0.35, grade of A+ in biology is 0.20 and grade of A+ in both statistics and in biology is 0.10. Find the probability that Amy will get at least one A+ between her statistics and biology classes.

Every Monday, James has a math class and a biology class. The probability that he will have his math homework done is 0.56 and the probability he will have his biology homework done is 0.45. If the probability he will have his biology homework done but not his math homework is 0.21, what is the probability he will have his math homework done given that he does not have his biology done?

This problem involves the career plans of students in a biology class. Assume that the class consists of 45 percent freshmen, 25 percent sophomores, 10 percent juniors, and 20 percent seniors. Assume further that 40 percent of the freshmen, 50 percent of the sophomores, 30 percent of the juniors, and 10 percent of the seniors plan to go to medical school. One student is selected at random from the class. (1) What is the probability that the student plans to go to medical school? (2) If the student plans to go to medical school, what is the probability that she is a junior?

A class in advanced physics is composed of 10 juniors, 30 seniors, and 10 graduate students. The final grades show that 5 of the juniors, 10 of the seniors, and 5 of the graduate students received an $A$ for the course. If a student is chosen at random from this class and is found to have earned an $A,$ what is the probability that he or she is a senior?
