7th - 11th grade

In Deal or no Deal 1 case is worth $1 Million. The other cases are not. The player selects a case, then begins to open the other cases. After 18 cases have been opened and found to not have the $1 Million, there are two cases left. The player then has a chance to switch cases. Should the player switch cases?


Hint: What is the probability the $1 million is in the original case, and what is the probability that it is in the other case? They're not the same!
