An individual is informed about presence of oil beneath his land. The

investment requirement for digging up the land is around 12 crores and if

he finds oil then he will generate profit of Rs. 180 crores. However, there

are only 15% chances that there will be oil, so under that situation he will

have to incur losses of Rs. 20 crores.

He has also got an offer to sell of the land and in that scenario; he will out

rightly make a profit of Rs. 50 crores.

Q-5

An individual is informed about presence of oil beneath his land. The

investment requirement for digging up the land is around 12 crores and if

he finds oil then he will generate profit of Rs. 180 crores. However, there

are only 15% chances that there will be oil, so under that situation he will

have to incur losses of Rs. 20 crores.

He has also got an offer to sell of the land and in that scenario; he will out

rightly make a profit of Rs. 50 crores.

For the above given situation

(a)What decision should the developer take under

i. Maximax criterion

ii. Maximin criterion

iii. Maximum likelihood criterion

iv. Even state of probabilities

v. Given state of probabilities

05

(b) i. What is the maximum amount that he should invest in hiring a market

specialist?

ii. Prepare a decision tree for even and given state of probabilities

Q-5

investment requirement for digging up the land is around 12 crores and if

he finds oil then he will generate profit of Rs. 180 crores. However, there

are only 15% chances that there will be oil, so under that situation he will

have to incur losses of Rs. 20 crores.

He has also got an offer to sell of the land and in that scenario; he will out

rightly make a profit of Rs. 50 crores.

Q-5

investment requirement for digging up the land is around 12 crores and if

he finds oil then he will generate profit of Rs. 180 crores. However, there

are only 15% chances that there will be oil, so under that situation he will

have to incur losses of Rs. 20 crores.

He has also got an offer to sell of the land and in that scenario; he will out

rightly make a profit of Rs. 50 crores.

For the above given situation
