In this problem, it is said that there are two teaching methods for a statistics class, online and face -to -face.
00:05
We are given information about how many students fail each class.
00:08
We're also given information about the chances of each of these classes being offered.
00:13
Now, we need to find the probability that a student who failed the course took the class online.
00:17
So let us consider a few events.
00:19
Let o be the event that the student took the class online.
00:22
Let f be the event that the student took the class face -to -face, and let us consider l to be the event that the student failed the course.
00:32
Then we need to find the probability that the student took the class online given that the student failed the course.
00:39
So p of o given l.
00:40
And to find this, we will use bays theorem.
00:44
To use bays theorem, we need a set of mutually exclusive and exhaustive events...
