Answer:
a)%85,5
b)%92,2
Step-by-step explanation:
a) To determine the probability of getting a hand with at least one face, we need to calculate the probability of the hand without any face firstly.

Then, we need to deduct this value from the probability 1

The probability of the hand with at least one face is %85,5.
b)To determine the probability of a hand with at least one ace and face we will track the same road again.

Then, we need to deduct this value from the probability 1

The probability of the hand with at least one ace and one face is %92,2.
