10. A cube has faces numbered 1 to 6. If you roll this cube 4 times, how many different outcomes are possible?
Georgia [21]

Answer: If we throw 4 cubes, there are 1296 different outcomes are possible.

Step-by-step explanation:

Given : A cube has faces numbered 1 to 6.

So the number of outcomes for throwing one die = 6

If we throw 4 cubes , then

According to the Fundamental counting principle,

That is, in this case, the apartments listed in the local newspaper and the internet. He will estimate a mean rent for the sample and, with this result, estimate the population mean rent.

The population is the bigger set available for Greg to do the estimation, and the set he wants to estimate a parameter from (in this case, the mean rent).

In this case, the population is all the apartments near the college.
