A.
3 red, 3 green, and 4 blue

B.
1 red, 5 green, and 4 blue

Answer 2

`Tyrell drew red marbles 9 times...Tyrell did this 100 times`
there are 100 total trials. Nine of them result in red

so the empirical probability of getting red is 9/100 = 0.09

multiply this with the number of marbles in the bag to get 0.09*10 = 0.9 which will round to 1 red marble in the bag

Answer 3

`Tyrell drew...green marbles 53 times`
we have 53 green out of 100 total

what is the empirical probability of getting green?

Answer 4

I think 53/100 = 0.53

0.53 * 10 = 5.3

Answer 5

good, that will round to 5 green marbles
