## Fruit Friends Riddle

If you and a friend have the same amount of apples, how many does she need to give you in order to have 10 more apples than her?

Hint:

She will always need to give you 5 apples. You both need at least 5 apples to begin with, but apart from that it doesnt matter exactly how many you each have. When she gives you 5 you will have 10 more than her because she will lose 5 and you will gain 5, resulting in a net difference of 10.

For example, if you each have 25 apples and she gives you 5 of hers, she will be left with 20 and you will now have 30, precisely 10 more than she has.

YES NO

## Switch Or Stick Riddle

There are three doors: Door 1, Door 2, and Door 3. Behind one of these doors lies eternal bliss, but behind the others lies eternal despair. You are allowed to choose any door, and you pick Door 1. Suddenly, Door 3 is swung open and revealed to be despair! You are give another choice: you may stick with the door you chose (1) or switch to the other (2). What should you do?

Hint:

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.

YES NO
