Step-by-step explanation:
Total marbles = 1 + 3 + 5 + 6 = 15
Probability of not blue marble = 10 / 15 = 2 / 3
The equation computed simply shows that the number of months will be C. 9 months.
<h3>How to solve the equation</h3>
From the information given, the equation 8m+3=75 models how many months, m, it takes a tree to reach a height of 75 inches after being potted.
Therefore, the number of months will be calculated thus:
8m + 3 = 75
8m = 75 - 3
8m = 72
m = 72/8
m = 9
The correct option is 9 months.
