The Alliance Corp. expects to sell the following number of units of copper cables at the prices indicated, under three different scenarios in the economy. The probability of each outcome is indicated. Outcome Probability Units Price A 0.50 295 $ 34 B 0.30 510 49 C 0.20 790 59 What is the expected value of the total sales projection?

Step-by-step explanation:

Given

The above data

Required

Determine the expected value E(x)

E(x) is calculated as thus;

Where f(x) represents the total sale of each outcome;

For A:

For B:

For C:

Hence, E(x):

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
