Abag contains 5 red marbles, 3 blue marbles, and 1 green marble. if one marble is removed from the bag, find the probability that it is not blue
a) 1/3
b) 6
c)3/2
d)2/3

d)

Step-by-step explanation:

We have the following information:

total of marbles: 5 + 3 + 1 = 9

The probability of removing one marble from the bag and not being blue is:

Where is the probability of removing a blue marble, which is:

So, the probability of removing one marble that is not blue, is the total probability (1) minus the probability of removing a blue marble:

Another way to reach the same result is as follows:

Since it can't be a blue one, we add the chances of it coming out red or green.

Thus:

Which is the same result we had found, so those are two ways of finding the answer to this problem.
