This is a method for finding the volume, in cubic feet, of the concrete walls:
• Find the area of the shaded region, known as the base of the
concrete walls.
• Multiply the area of the shaded region by the height of the wall.
Use this method to find the volume, in cubic feet, of the concrete walls.

Step-by-step explanation:

From the question,

orange jelly beans= 7

Cherry jelly beans =9

Lemon jelly beans = 3

Licorice jelly beans = 15

Blueberry jelly beans = 6

Total jelly beans = 40

The probability of choosing the first cherry jelly beans will be = 9/40

After the first one is chosen, there'll be 8 cherry jelly beans and total of 39 left. The probability of choosing the second one will be = 8/39

The probability of choosing two cherry jelly beans in a row will be:

= 9/40 × 8/39

= 72/1560

= 0.046
