Jack and Jill are playing a game. They flip 2 coins and if BOTH coins land on HEADS, Jill wins.

 If one lands on tails and one lands on heads, Jack wins. If both land on tails, no one wins.

 Is this a fair game? Why or why not? 

It is not a fair game because Jill has a probability of 1 in 4 to get 2 heads. Jack wins if

 there are 1 of each. That means the probability that Jack will win is 2 out of 4 (or ½ ).
