Answer : Probability of not pulling out a green marble is 65 percent.
Step by step explanation:
Step 1 : Count up all the marbles.
3+8+7+2= 20 marbles in total
Step 2 : Now find the amount of marbles which are not green, subtract.
20 - 7 = 13
Step 2 : Find what percent 13 is of 20 to get the probability.
13 divided by 20 = 0.65
Therefore the probability of not pulling out a green marble is 65 percent.
Have a nice day ;)
