Julio sells computers at an electronics store. Let the random variable C represent the number of computers that Julio sells in one week. The following table shows the probability distribution of C.

Answer:

the expected value of Julio earning for one week is $1,462

Explanation:

The expected value of Julio earning for one week is shown below:

But before that

First determine E(c)

= 1 × 0.08 + 2 × 0.16 + 3 × 0.21 + 4 × 0.3 + 5 × 0.18 + 6 × 0.03

= 3.31

The earning is

= $800 + $200 C

= $800 + $200 × 3.31

= $800 + $662

= $1,462

Hence, the expected value of Julio earning for one week is $1,462
