Probability Puzzles

This app offers over 80 probability math puzzles in three levels. I've included a math parser so that you can type equations as answers: if the answer is 0.49^2, for example, you can enter 0.49^2 or 0.49*0.49 without having to work out the multiplication yourself. Some of the puzzles are very challenging, even for people who have studied college-level probability -- try answering them all! If you get stuck, there's a hint at the bottom of each page, and you can always skip puzzles (and return to them later) by swiping horizontally. Have fun!
