Question

PLS HELP I DON’T UNDERSTAND

Answer 1

The question asks for the probability that a marble is NOT YELLOW

Total Marbles: orange+yellow+blue=7+3+2=12

We need to count all marbles except yellow:

orange+blue=7+2=9

Now to find the probability that is NOT YELLOW:

`(All Marbles Except Yellow)/(Total Marbles)`=
`(9)/(12) = (3)/(4)`

Answer is 3/4

Hope it helps!
