A bag contains 7 red marbles, 9 blue marbles, and 6 green marbles. what is the probability of choosing a marble that is not gree
skad [1K]
Probabilities! In order to find the answer you first have find out the total amount of marbles that you have. So:

[7 + 9 + 6] = 22

This number will go into the denominator. 

The next step is to find how how many marbles are not green. To do that you simply add the red marbles and the blue marbles. So:

[7 + 9] = 16

This number will go in the numerator.

The probability of you choosing a marble that is not green is 16/22. You can also simply this and it would be 8/11.

Is it possible for two linear functions whose graph are parallel to have the same y-intercept
soldier1979 [14.2K]
If you have e two linear functions and on a graph they are parallel that means they have the same slope with different y intercepts. If they are parallel and have the same y intercept then they would be the same graph. So no it’s not possible because there would not be two different graphs/functions; they would be exactly the same.
