One professional basketball player typically attempts eight free throws per game. Let X represent the number of free throws made out of eight. The distribution for X is shown in the table. Which of the following is the correct interpretation of P(X ≤ 3)? The probability of the number of free throws made out of 8 is at most 3. The probability of the number of free throws made out of 8 is at least 3. The probability of the number of free throws made out of 8 is lower than 3. The probability of the number of free throws made out of 8 is higher than 3.

A certain disease has an incidence rate of 0.2%. The false negative rate is 8%, and the false positive rate is 3%. Calculate the probability that a person who tests positive actually has the disease. 0.0848 Note: The incidence rate is the probability that a random person gets the disease. The false negative rate is the probability of getting a negative result given that the person has the disease. The false positive rate is the probability of getting a positive result given that the person does not have the disease.
