8. Two cards are drawn without replacement from an ordinary deck. Find the probability that
a) the second is a 7 given the first is also a 7. _____
b) the second is a queen given the first is not a queen. _____
c) two spades are drawn. _____
9. Two-thirds of the population are on a diet at least occasionally. Of this group, 4/5 drink diet soft drinks, while 1/2 of the rest of the population drink diet soft drinks. Complete A tree below (labels AND probabilities) and then answer the questions below.
Let D = those who diet, then D’ = _________________________ (in words)
Let S = those who drink diet soft drinks, then S’ = ________________________ (in words)
10. Draw and Shade Venn Diagrams below to represent the set given
A. A∪B′
B. (A∪B′)∪C
C. (A∪B′)∪C′
D. (A∪B′)∩C
E. (A∪B′)∩C′
F. A∩B′
G. (A∩B′)∪C
H. (A∩B′)∪C′
I. (A∩B′)∩C
J. (A∩B′)∩C′
Solutiona) Number of ways to make a sum of 5 = (1,4), (2,3), (3,2), (4,1)So, probability of a sum of 5 = 4/36 = 1/9b) Number of ways to make a sum of 7 = (1,6), (2,5), (3,4), (4,3), (5,2),…
