Given: The probability that an adult possesses a credit card P(A)= 0 .70

The probability that an adult  does not possess a credit card

By assuming the independence, the probability that the first adult possesses a credit card and the second adult does not possess a credit card is given by :-

Hence, the probability that the first adult possesses a credit card and the second adult does not possess a credit card is 0.21.
