Stats Chat: The Monty Hall Problem
This game has a trick to it! Can you figure it out? You can discover this trick using statistics and tree diagrams.Delta Math Practice - 15.4 Find Probabilities Given Probabilities
Just for fun part 2: Monty Hall Problem explained
Subject: Re: Why use multiplication to find the probability of two events
Thinking of probability as the fraction of the time that something will happen may make this clearer.
If event A happens 1/2 of the time, and event B happens 1/3 of the time, and events A and B are independent, then event B will happen 1/3 of the times that event A happens, right?
And to find 1/3 of 1/2, we multiply.
The probability that events A and B both happen is 1/6.
