In a red zone area from covid, it is known that there are 3 people who become Covid-19 Asymptomatic Persons (AP) out of every 8 people present. An officer randomly selects 3 people to be swab tested. If X is a variable that represents the number of people who became AP, a. Find the number of possible x values of the variable X, and calculate the probability of each x value. b. Determine what is the probability that the officer will get at least 1 person who becomes the AP.

A study of the incoming freshman class at a university found that 60% of the students had taken AP Calculus in high school, 55% had taken AP English in high school, and 20% had taken both AP Calculus and AP English. One incoming freshman is randomly selected from the population of incoming freshman.
