Multiplication Rule


Here you will learn how to quickly calculate the probability of the intersection of multiple independent events without building a frequency table.Finding the probability of getting two or three heads in a row when flipping a fair coin is enough by building a frequency table. However, the process becomes somewhat unwieldy when the experiment is more complex, such as calculating the probability of pulling 3 queens in a row from a standard deck of cards. Building a frequency table for all 52 cards would be time consuming at best.
