I WAS DELIVERING A PIZZA TO AN OLD APARTMENT BUILDING IN A BAD AREA OF TOWN WHEN I PUSHED THE BUTTON TO CALL THE ELEVATOR THE DOO RIDDLES WITH ANSWERS TO SOLVE - PUZZLES & BRAIN TEASERS

The answer may surprise you: switch. Due to something called the Monty Hall Paradox, you will statistically have a better chance of making the "correct" choice. The concept is as follows:

Door 1 Door 2 Door 3

All have an equal chance to be correct:

Door 1: 1/3 Door 2: 1/3 Door 3: 1/3

After choosing Door 1, the remaining two have a 2/3 chance of containing the right choice:

Door1: 1/3 Doors 2 3: 2/3

If Door 3 is removed, the probability does not shift to 50:50. Instead, it is:

Door 1: 1/3 Door 2: 2/3

Thus, you should switch. Did you answer this riddle correctly?
