In a group of 40 people, 10 are healthy and every person of the remaining 30 has high blood pressure, a high level of cholesterol or both. If 15 have high blood pressure and 25 have high level of cholesterol, how many people have high blood pressure and a high level of cholesterol? Use information given in to answer the following questions i. If a person is selected randomly from this group, what is the probability that he/she has high blood pressure (event A)? ii. If a person is selected randomly from this group, what is the probability that he/she has high level of cholesterol (event B)? iii. If a person is selected randomly from this group, what is the probability that he/she has high blood pressure and high level of cholesterol (event A and B)? iv. If a person is selected randomly from this group, what is the probability that he/she has either high blood pressure or high level of cholesterol (event A or B)? v. Use the above to check the probability formula: P (A or B) = P(A) + P(B) - P(A and B).
