Answer 1

Answer:

about .63 or 17/27

Step-by-step explanation:

I know the probability is about .63 because I found the probability of not choosing a blue marble, which is the same as finding the probability of choosing a red, green or yellow marble. There are 4 red marbles, seven green marbles and 6 yellow marbles. There are 10 blue marbles. I knew there was 27 marbles in all, so I found the probability of choosing a red, yellow or green marble.

4+7+6

_____ = 17/27 ~ 0.62962962963

27

In conclusion, the probability of the event of not choosing a blue marble is about .63 or 17/27.

Answer 2

Answer:

17/27
