Answer:
Helene is right
Step-by-step explanation:
Mathematically, the expected values is defined as the sum of all the possible outcomes that an event can have times the probality of the respective outcome:
x = ∑ p *i,
where x is the expected value, i represents every outcome that can occur, and p is the probability of said outcome.
Now, for the case of a dice, the expected value would be:
x = 1 * 
+ 2 * + 3 * + 4 * + 5* + 6 * ,
as every outcome has the same chance of happenning. Solving we get that:
x= *(1 +2 +3 +4+5+6) = * 21 = 3.5

the volume of the cube is: 512 cubic feet
Step-by-step explanation:
Given
Length = l = 8 feet
The formula for the volume of a cube is given by:
In case of a cube, the length, width and height are equal so the volume will be:
Putting l = 8
Hence,
the volume of the cube is: 512 cubic feet
