Using the probability table, it is found that:
- a) There is a 0.25 = 25% probability that this couple spends 45 dollars or more.
- b) The expected amount the couple actually has to pay is $36.85.
Item a:
To find the probabilities involving the total cost, we have to <u>add the variables X and Y</u> from the table, then:
The probability involving <u>values of 45 or more</u> is:
0.25 = 25% probability that this couple spends 45 dollars or more.
Item b:
For a <em>discrete distribution</em>, the expected value is the <u>sum of each outcome multiplied by it's respective probability</u>, hence, involving the 10% discount for prices above $45:
The expected amount the couple actually has to pay is $36.85

Step-by-step explanation:
Answer:
132,000
Step-by-step explanation:
The computation of the amount of income or loss is shown below:
= (Offer price - variable cost per unit) × number of units of production
= ($17 - $11) × 22,000
= $6 × 22,000
= $132,000
We do not considered the fixed cost and the domestic unit sales as it is not relevant for the computation part. Hence, ignored it
Offer price - variable cost per unit shows the gain per unit arise
