suset randomly pulled a marble 60 times from a bag replacing the marble after each pull. blue was pulled 25% of the trials red was pulled 15% of the trials the remaining trials she pulled green. how many times could suset be expected to pull a green marble after 300 trials?

it gonna be 520

Step-by-step explanation:

i think

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
