This example will show us how to find the total number of different monograms that can be created.
00:08
A monogram, if you were not sure, is just your first, middle, and last initial.
00:12
So it's a three -letter sequence.
00:15
Those letters could possibly be anything.
00:17
For example, my initials would be mjd, michael john dunn.
00:24
They could use the same letter more than once.
00:27
So, for example, maybe your name is jeremy jason jones.
00:32
So it doesn't have to be a different letter each time.
00:35
Names could be repeated with the same initial.
00:39
And i'm going to illustrate how this works before i just show you the math really fast.
00:43
I'm going to do this by showing you a sample space in the form of a probability tree.
00:47
For example, our first initial could be a, could be b, could be c, could be d.
00:54
It could be anything all the way up to z...
