Events: D - Drinks, S - Smokes, DS -Drinks and Smokes (a) Fill in the following blanks and use these values to complete the table belov Probabilities: P(D) Probabilities Smokes (S) Drinks (D) P(S) P(DS) Not Smokes (3) Total P(D) P(D)- 1.00 P(DS) P(DS)- PDS) = P(S) Not Drink (D)P(DS)- P(S) Total (b) What is the probability the person does not drink? (c) What is the probability the person drinks or smokes? (d) If the person drinks, what is the probability that he or she smokes? (e) If the person does not smoke, what is the probability that he or she drinks? (f) Are the events "Drinks" and "Smokes" mutually exclusive? (State Ύes" or No" and explain.)
