Hello, Tomm!

I think I've got it . . .

The jars look like this:Tassie decides to run a competion at her chocolate factory.

The prize is a years supply of her best sellers: Rockies, Delights, Nutbix and Creams.

She has 4 jars, one with R & D, one with D & N, one with N & C and one with C only.

~ The chocolates are identical in size and are wrapped in identical foil.

~ The jars are lablled: R & D, D & N, N & C, and C, but no label is on the correct jar.

~ The aim of the competion is to identify the jars correctly after selecting

. . and unwrapping as few chocolates as possible.

~ No contestant sees what another contestant unwraps.

A) Emily unwraps a chocolate from the jar labelled R & D, and it is a N.

From the jar labelled D & N she gets a C, from the jar labelled N & C, she gets a N,

and from the jar labelled C she draws a R.

Show how Emily can correctly relable the jars.
