Question
Please solve the following question and all of it parts (part a and b) Also please provide explanation how you got to each answer and what was the thinking?
Question 1. Consider a game where you can pay either $2 to flip two coins, or $3 to flip three coins, and where you
win a prize depending on the number of heads that show:
If three heads show, you win $7.
If two heads show, you win $3.
If one heads shows, you win $2.
. If no heads show, you don't win anything.
(a) Is it better for you to pay $2 or $3 (in terms of your expected winnings)? Justify your answer.
(b) Suppose that your friend also plays this game, but they randomly pick between paying $2 or $3 instead (so there
is a 50% probability they flip two coins, and 50% they flip three coins).
If you know that they neither won nor lost money (i.e. net winnings is $0), is it more likely that they flipped two
coins or three when they played the game? Justify your answer.
