The formula ogf a volume of a pyramid:

B - area of a base
H - height
We have a base length a = 5 in and a height H = 9 in.

Substitute:

Calculate the volume:

Answer:
62.22%
Step-by-step explanation:
First, find how many total marbles there are:
12 + 11 + 17 + 5
= 45
Then, find how many marbles that are not blue:
12 + 11 + 5
= 28
Then, divide 28 by 45, and multiply by 100
(28/45) x 100
= 62.22% is the probability of not choosing a blue marble
The answer is......... 27
