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:

$\frac{All Marbles Except Yellow}{Total Marbles}$= $\frac{9}{12} = \frac{3}{4}$

Answer is 3/4

Hope it helps!
