Contains three marbles one red one green one blue we want to look at an experiment we're drawing one marble replacing and drawing a second time that we're describe that sample space so in this case we're gonna look at like a first draw and a second draw i'm gonna do it as a bit of a mapping diagram contains three marbles one first draw we have choices of either red green or blue so i'll call it r, g, and b.
00:27
For my second draw, because we're replacing, we get the same exact choices.
00:32
We get red, green, blue.
00:34
And so if we draw green first, then we get red, green, and blue.
00:41
And then the same thing happens here.
00:43
We get three choices.
00:44
We get red, green, and blue.
00:47
So the sample space is either going to be red red, red green, red blue, green red, green green, green blue, blue red, blue green, and blue blue.

So we get a total of nine...
