If all outcomes are equally likely, then the probability of an event E occurring is given by the formula:

• P(E) = (number of ways P can occur) / (total number of outcomes)

• P(E) = (number of ways D can occur) / (total number of outcomes)

• P(E) = (number of ways C can occur) / (total number of outcomes)

• P(E) = (number of ways R can occur) / (total number of outcomes)

• P(E) = (number of ways E can occur) / (total number of outcomes)

The probability of rolling a 6 on a six-sided dice is _____. 

• 17%

• 1/5

• 33%

• 1/6

• 16.5%

What is the BEST definition of compound interest?

•  The account accumulates a constant amount of interest per time interval.

• The account accumulates a variable amount of interest per time interval.

• Interest earned by an account is multiplied with a balance prior to interest earned in the next period

• Interest earned by an account is added to the balance before interest is earned in a next time period.

• Interest is compounded daily, resulting in larger growth of an account balance over time.
