Question

The table below shows the number of marbles of different colors in a bag:




.Color of Marbles
.Number of Marbles


Pink 5
Blue 2
Green 3


Ursula draws a marble from the bag randomly without looking. She then draws another marble from the bag without replacing the first one. Which expression shows the probability of drawing green marbles in both the trials?

A. 3 over 10 multiplied by 2 over 9

B.3 over 10 multiplied by 2 over 10

C.3 over 10 added to 2 over 9

D. 3 over 10 added to 2 over 10

Answer 1

There are 5+2+3 = 10 marbles total

The probability of picking green is 3/10 because there are 3 green out of 10 total

We do NOT replace the marble we picked, so we have 10-1 = 9 marbles left. There would be 3-1 = 2 green marbles left

On the second pick, the chances of getting green is 2/9 because there are 2 green out of 9

At this point, we multiply out the probabilities

(3/10) * (2/9)

Answer 2

most books would want you to multiply out (3/10) * (2/9) but it appears your book wants you to stop here

any one else wants to say what they think? the answer
