chance of getting a red marble is 8/50
8/50 = 80/500
Answer is 80
We would need to multiply the number of trials (which is 500) by the probability of choosing a red in 1 try from the information given.
There are 50 in total, and 8 of them are red, so:
Now we multiply this with 500 to get:
The correct answer is A.
It's A: 80 on E2020
hope this helps you pupy!

I just took the test and got 100%
Marcie should expect 80 red marbles. Correct answer is (A).
First we need to calculate the probability of red marble to come from the bag of 50 marbles.
Now the chances of getting red marble after 500 trail is calcualted as
Therefore the correct answer is (A).
The answer would be 80
The reason it would be 80 is because their are 8 red marbles so doing one trial it would be a 8/50 chance. if you add a zero to both that gives you your answer.
Find out how many times 50 goes in 500 500 divided by 50 = 10 Multiply by 8 to get the total number of red
8x10 = 80 red marbles
then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left
divide by both sides by 2 to get your answer so that you can get your answer
