Click on this link to see a 30 second video clip on where Frequency Analysis was used in The Imitation Game (2014):
https://youtu.be/J4J8ak6tM6g

Since I didn't manage to successfully demonstrate how to "break" a classical cipher using frequency analysis during this week's lecture, I thought I might as well follow up with this class demo via online resources instead, so that those who are interested in Cryptography could benefit from investigating how Probability & Statistics can and have been used in Cryptography.

With that said, if you are interested in investigating how Frequency Analysis works, feel free to read the detailed explanation in the link below:
http://crypto.interactive-maths.com/frequency-analysis-breaking-the-code.html#intro

P.S. attached is the SUCCESSFUL demo of how to "break" the classical cipher (taken from the link above) that I failed to "break" during our lecture this week.

Warm regards,
