Step-by-step explanation:
Interest earned is like bonus money the bank pays you just for keeping money
![\mathrm{Compund\:Interest\:Formula}:\quad A = P { \left( 1+ \dfrac{ r }{ n } \right) }^{ nt }](https://tex.z-dn.net/?f=%5Cmathrm%7BCompund%5C%3AInterest%5C%3AFormula%7D%3A%5Cquad%20A%20%3D%20%20P%20%7B%20%20%5Cleft%28%201%2B%20%5Cdfrac%7B%20r%20%20%7D%7B%20n%20%20%7D%20%20%20%20%5Cright%29%20%20%20%20%7D%5E%7B%20nt%20%20%7D)
P: the starting balance of the account (also called initial deposit, or principal)
A: the new balance in the account after N years.
t: the number of years or time
r: the interest rate, (in decimal form)
n: the number of times the interest is compounded each year.
Annually = each year = 1
P =$300, r = 7%, t = 2, n = 1, A = ?
Substitute the numbers into the "Compound Interest Formula".

12 possible outcomes
any number less than 9 is 8 and below
8 sides of the dice are less than 9 out of 12 total sides
8/12 is the chance you’ll roll lower than 9
2/3 or 66% chance you’ll roll a number lower than 9
