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

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

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

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
