Call a mathematician, we've got a Monty Hall problem

From Nights, 10:30 pm on 23 May 2024

On Wednesday night's quiz, we played some music and listeners had to identify what instrument was playing.

During that quiz, when eliminating one of the three options, we encountered the classic Monty Hall problem.

Lo and behold, we got not only a text, a comprehensive email from a listener, explaining in excellent clear terms the Monty Hall Problem and why you should do what you should do in this situation ... it was from Dr Chris Tuffley, a senior lecturer in mathematics at Massey University.

He helps Emile Donovan with his math and explains how the problem can be tackled.
