Answer 1

Option (D) is correct.

Step-by-step explanation:

For Aline:

E(v) = Earning × Probability of earning + Don't believe earning × probability

= 200,000(0.5) + 0(0.5)

= 100,000

For Saraf :

E(v) = Earning × Probability of earning + Earning × probability

= 0.75(100,000)+0.25(10,000)

= 77,500

Therefore, the expected value of the undertaking is according to Aline, is $100,000.
