Because the distribution of Mercedes CLK350 Coupe in normally distributed, you can use the normalcdf function on your calculator.

On a TI-84, normalcdf is under DISTR

in this case the low is 43000 because you are finding the probability that the price is that or higher. The high would be any really large number (ex. 1000000000). And the mean and standard deviation are already given to you.

so it will look like:
normalcdf(43000, 100000000, 44520, 2981) then press enter to get the answer!
