Using the given discrete distribution, it is found that the expected value is of $863.93.
<h3>What is the mean of a discrete distribution?</h3>
The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.
In this problem, the distribution of costs is given by:
Hence, the expected value is given by:
E(X) = 0.87 x 986 + 0.13 x 47 = $863.93.

Answer:
1/3(x-1)
Step-by-step explanation:
1/3x - 1/3
Both terms have a greatest common factor of 1/3
1/3 *x - 1/3 *1
Factor out a 1/3
1/3(x-1)
