Answer:

Hence the expected value for the contractor for sales is 15,300 $.

Step-by-step explanation:

Given:

Winning $27000 is 0.7 and losing 12000 $ of it about 0.3

To find :

Expected value for the contractor for sales.

Solution:

Th expected value is the average occurred  of the event.

<em>{Suppose </em>

<em>a series of number like 10,30,30,30,30,60,78.</em>

<em>for this  expected value will be</em>

<em>(10+30+30+30+30+60+78+78) / 8</em>

<em>=10(1/8)+30(4/8)+60(1/8)+78(2/8).</em>

<em>78 ,10 ,30 and 60 are just like cost and 1/8 ,4/8,2/8 are probabilities of respective cost</em>.

}

Similar for given values

Expected value with probability is =

Winning probability *cost of winning +(-losing probability * losing cost)

losing means negative impact on value so it is negative

=27000*0.7-12000*0.3

=18900-3600.

=15300 $.

r = 275 ÷ -55 = -5

or, r = -55 ÷ 11 = -5

Therefore, r = -5
