3 1/2 is less because 1 liter in cups is 4.227
Answer:
c = 6
Step-by-step explanation:
2(4 + cy) = 12y + 8
8 + 2cy = 12y + 8
12y + 8 = 8 + 2cy
12y - 2cy = 8 - 8
2y (6 - c) = 0
Divide through by 2y
(6 - c) = 0
c = 6
Assuming that each marble can be picked with equal probability, we notice that there is a total of

marbles, of which 2 are red.
So, the probability of picking a red marble is

In fact, as in any other case of (finite) equidistribution, we used the formula

y = 45
multiply both sides by 5 to eliminate the fraction
90 = 2y ( divide both sides by 2 )
45 = y
