You can solve many simple probability problems just by knowing two simple rules:

<span> The probability of any sample point can range from 0 to 1.<span> The sum of probabilities of all sample points in a sample space is equal to 1. </span></span>

The following sample problems show how to apply these rules to find (1) the probability of a sample point and (2) the probability of an event.

Holly wants to save money for an emergency. Holly invests 1,500 in an account that pays an interest rate of 6.75%. How many year
lina2011 [118]
The formula is
A=p (1+r)^t
A future value 7300
P present value 1500
R interest rate 0.0675
T time?
7300=1500 (1+0.0675)^t
Solve for t
Divide both sides by 1500
7300/1500=1.0675^t
Take the log for both sides
Log (7300/1500)=t×log (1.0675)
Divide both sides by log (1.0675)
T=log(7,300÷1,500)÷log(1.0675)
T=24.2 years round your answer to get 24 years

Hope it helps!
