The probability of winning of a person is 6/11 and at a result he gets...
Solution:
Given, probability of winning of a person = 6/11
Amount received by the person = Rs. 77/=
To find: Expectation of the person

Calculation:
The formula to find the expectation of a person is:
Expectation = (Amount received x Probability of winning) - (Amount lost x Probability of losing)

Here, the probability of losing = 1 - Probability of winning
= 1 - (6/11)
= 5/11

Substituting the given values in the formula, we get:
Expectation = (77 x 6/11) - (0 x 5/11)
= 42

Therefore, the expectation of the person is Rs.42/=. Hence, option B is the correct answer.

Conclusion:
The expectation of the person who wins with a probability of 6/11 and receives Rs.77/= is Rs.42/=.

If we assume that the total rs is 110 then the 6 th part is rs 66 fos the maximum probablity is fulfilled then but he gets rs 77 . so its expectation should be less than rs 66 77-66 =11 66-11=55 therefore it should be less than 55 (b) this is a shortcut for solving
