Now here, this problem we want to have a random variable for the number of times you'll miss class this semester.
00:05
We'll prepare a table and a probability distribution for this.
00:12
And so let's look at our probability distribution first.
00:16
Now, this is all subjective here, but let's say there's a 80 % chance that you miss zero times.
00:24
And then, again, i'm just making these numbers up here.
00:26
Let's try to have a little fun, so a 12 % chance you miss once.
00:29
We've got 8 % left over, so make sure that these all add up to 1 whenever you finish.
00:38
That should be 0 .07, not 0 .7.
00:44
All right.
00:46
And so here's a probability distribution.
00:48
Okay, an 80 % chance you don't miss at all...
