Answer: CURRENT AGES: C = 35, D = 5 AGES IN 5 YEARS TIME: C = 40, D = 10
Step-by-step explanation:
We need to use algebra here.
Let C = Coffee's age
Let D = Daughter's age
C = 7 x D
C + 5 = 4 x (D + 5)
C + 5 = 20 + 4D
C = 15 + 4D
7D = 15 + 4D
D = 5
C = 7 x 5
C = 35

Answer:
B. The individual events are dependent. The probability of the combined event is 3.772%.
Step-by-step explanation:
The individual events are dependent because you would have to draw 2 red candies in a row. After the first drawing, there would be one less red candy in the bag, which would affect the second drawing.
First drawing probability: 11/54, or 20.370%
Second drawing probability: 10/54, or 18.519%
Combined probability: 20.370*18.519 = 3.772%
