Q:

Logical puzzle

At a restaurant, how could you choose one out of three desserts with equal probability with the help of a coin? What if the coin is biased and the bias is unknown?

Answer

Our solution:


Toss the coin twice.
Let TH, HT and TT correspond to the three choices.
And if you get HH, just repeat (so it takes 8/3 tosses on average).


BIASED COIN

If the coin was biased, TH and HT would occur with equal probability.
So you could assign THHT, HTTH and THTH to the three choices, with other 4-toss outcomes rejected.
Or you could assign HTT, THT and TTH to the three choices, with other 3-toss outcomes rejected.

Q:

Logical puzzle

You work at a fruit factory.
There are 3 crates in front of you. One crate contains only apples. One crate contains only oranges. The other crate contains both apples and oranges. And each crate is labeled. One reads "apples", one reads "oranges", and one reads "apples and oranges". But the labeling machine has gone crazy and is now labeling all boxes incorrectly. If you can only take out and look at just one of the pieces of fruit from just one of the crates, how can you label ALL of the crates correctly?

Answer

Our solution:


Take a piece of fruit from the "apples and oranges" crate. If it's an apple then you know that is the "apples" crate since ALL THE CRATES ARE LABELED INCORRECTLY. This means the crate marked "apples" must be "oranges" and the crate marked "oranges" must be "apples and oranges".

Logical puzzle

John, Jenita, Maria and Julie went to a shop. Each picked a colorful ball of a different favorite color. The colors are Yellow, Violet, Green and Red. John and Maria both do not like violet. The person who likes red is a girl. Jenita likes green, but it is not her favorite color. Jenita's favorite color is either green or yellow, although she can have only one favorite color. John likes red, but it is not his favorite color.

Answer

Jenita's color should be yellow. John's color cannot be violet and red, it might be yellow or green. As Jenita's color is yellow, so John's color will be green. Maria's do not like violet, so her color must be Red. Then Julie's color is violet.
