Two coins tossed simultaneously.A person receive Rs.8 each head and losses Rs.10 for each tail.Find expected value of the amount
Two coins tossed simultaneously. Let be the sample space .
Then { }
Let us define a random variable is defined by
Net amount gain ,
Then, .
And probability of each point is given below,
Now let us draw a table of distribution function as follows
Then
Therefore expected value of amount is
