Question

The probablility that a person drinks at least five cups of coffee per day is .24, and the probability that a person has high blood pressure is .08. Assuming that these two events are independent, find the probability that a person selected at random drinks less than five cups of coffee per day or has high blood pressure. Explain how to get the answer.

< 5cups = (1 - .24)

Either-or probabilities are found by adding the individual probabilities.

Answer 2
