HELP!! attendance at football game, what is the probability

[princesssonya]

I don't even know how to start this question it has 3 parts a, b, and c, if someone could walk me through a, i may be able to do the rest please help me

The attendance at football games at a certain stadium is normally distributed, with a mean of 55,000 and a standard deviation of 4500.

a. What is the probability of the attendance exceeding 60,000?

Now, I kow i need to do the normal distribution curve thing, and use the z chart im just not sure how to go about that and how to set up and plug my numbers in on the curve ?? Im so lost pease help :shock:

\(\displaystyle \L\\z=\frac{x-{\mu}}{\sigma}\)

\(\displaystyle \L\\\frac{60000-55000}{4500}=1.\overline{11}\)

Look up the corresponding probability in the table and subtract from 1.

You subtract from 1 because it says "greater than" 60000.
