Answer with Step-by-step explanation:
We are given that
Number of ace cards=3
Number of face cards=5
Number of non-face cards=11
When we draw randomly 3 cards.
Z=5(number of aces)+4(number of other face cards)
We have to determine the possible different values for the random variable Z
Number of ace cards=3, number of other face cards=0
Z=5(3)+4(0)=15
Number of ace cards=2, number of other face cards=1
Number of ace card=1, number of other face cards=2
Z=5(1)+4(2)=13
Number of ace card=0, number of other face cards=3
Z=5(0)+4(3)=12
