(a) 0.698

(b) 0.302

Explanation:

(a) Probability that a subscriber rented a car during the past 12 months for business or personal reasons:

= Rented car during the past 12 months for business reasons + rented a car during the past 12 months for personal reasons - rented a car during the past 12 months for both business and personal reasons

= 0.458 + 0.54 - 0.30

= 0.698

(b) Probability that a subscriber did not rent a car during the past 12 months for either business or personal reasons:

= 1 - Probability that a subscriber rented a car during the past 12 months for business or personal reasons

= 1 - 0.698

= 0.302
