Answer:

The answer is "\frac{2}{15}" .

Explanation:

\to x = 0, 1, 2, 3, 4, 5\\\\\to p(x) \ for \ x  \ =   0, 1, 2, 3, 4, 5 = 0\\\\ \to c, 2c, 3c , 4c, 5c = 1\\\\\to 0 + c + 2c + 3c + 4c + 5c = 1\\\\\to 15c = 1\\\\\to c = \frac{1}{15}\\

\to p(x) \ for \ x  \ =   0, 1, 2, 3, 4, 5 = 0\\\\ \to \frac{1}{15}, \frac{2}{15}, \frac{3}{15}, \frac{4}{15}, \frac{5}{15}  

\to P(X=2)=\frac{2}{15}

BEGINNING INVENTORY

70 units at $150 = $10,500

cost of BI                 $3,600

Contribution Begining Inventory         $6,900

get the production of this year contribution

Sales Units              150

Direct Materials 25

Direct Labour     10

Variable MO       15

Variable S&A       6

Total Variable           56

Contribution            94

Unit produced 450

Contribution Produced units 42300

Second, the operating income:

     Contribution Begining Inventory         $6,900

     + Contribution Produced units             42,300

                                    Total contribution = 49,200

 Fixed Cost

fixed MO 15,600

fixed S&A 13,000

                                       Total Fixed Cost    28,600

                                     Operating Income 20,600

= $100,000

And, for Navy, it is

= $400,000 - $159,000

= $241,000

We simply applied the above formula to compute the gross profit
