Question

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

Answer 1

Bryn draws a marble from the bag randomly without looking. He then draws another marble from the bag without replacing the first one. Which expression shows the probability of drawing blue marbles in both the trials?
8 over 13 multiplied by 7 over 13
8 over 13 added to 7 over 12
8 over 13 multiplied by 7 over 12
8 over 13 added to 7 over 13

Answer 2

what is the probability of getting a blue marble before any marble was drawn?

Answer 3

8 over 13

Answer 4

Answer 5
