The probability of not drawing a black marble is 4/5
The probability of drawing a red marble is 3/10
<h3>What are the probabilities?</h3>
Probability determines the odds of the occurrence of a random event. The probability the event occurs is 1 and the probability that the event does not occur is 0.
Probability of not drawing a black marble = total marbles that are not black / total number of marbles
(5 + 3) / (5 + 3 + 2) = 8/10 = 4/5
The probability of drawing a red marble = total number of red marbles / total number of marbles
= 3/10

Volume = length x width x height
we are told that the bottom fits 25 blocks, so that 5 x 5, then we are told the height is 3 feet, so:
5 x 5 x 3
75ft
Answer:the first place seller receives $56
The second place seller receives $28
The third place seller receives $20
Step-by-step explanation:
Let x represent the amount that the first place seller would receive.
Let y represent the amount that the second place seller would receive.
Let z represent the amount that the third place seller would receive.
The second place winner will receive 8 more dollars than the third place winner. This means that
z = y - 8
The first place seller will receive twice as much as the second place seller. It means that
x = 2y
The profit portion they will share is $ 104. It means that
x + y + z = 104 - - - - - - - - - - - 1
Substituting z = y - 8 and x = 2y into equation 1, it becomes
2y + y + y - 8 = 104
4y = 104 +8 = 112
y = 112/4 = 28
x = 2x = 2 × 28
x = 56
z = y - 8 = 28 - 8
z = 20
