Suppose you are offered this opportunity: You can place a bet of $10 and someone else tosses a coin. You win an additional $15 if heads occur, and you lose your $10 if tails occur What is the expected value of this game? Should you play?

 

 

Solutions

Expert Solution

Given:

Bet is of $10.00

If head occurs then additional winning of $15.00.

If tail occurs then losing $10.00.

 

We know

Probability of occurring head when tosses a coin = ½

Probability of occurring tail when tossing a coin = ½

 

Expected value of game = (1/2 × 15 – 1/2 × 10) $

                                           = $ 2.5

 

Expected value of this game is $ 2.5.

 

I should play the game because our expected value if positive which means that chance of profit of money is more.


Expected value of this game is $ 2.5.

Suppose that you tossed a coin 1000 times in which 560 of the tosses were heads while 440 were tails. Can we reasonably say that the coin is fair? Justify your answer. Hint: use the concept of p-values. To evaluate the resulting probability, use an approximation by way of the CLT. Why does this offer a good approximation? Use a z-table or R to evaluate the N(0,1) cdf.
