1. In order to start this puzzle, Junpei must have a coin bag in his possession and use it on the middle machine. Although it may look like he needed to get the same reels in a row to win by guessing using luck and timing, the buttons on the machine are really there to be pressed in a certain order shown by the secret code mentioned earlier.
2. The manager of a casino would like to add a new type of slot machine game to the casino. Given below are the probability distributions for her top four choices. The values of the random variable are the amounts the casino would either gain (positive values) or have to pay out (negative values).

I've got everything finished for the program, but it's telling me that the 'else if' won't work because I don't have an 'if' but I have the 'if' right above it. I tried making them all 'if' to see.

Couldn’t get formatting on here so make sure to format 🙂
