An email message can travel through one of two server routes.
00:05
The probability of transmission error in each of the servers and the proportion of messages that travel each route are given in the following table.
00:12
Assume the servers are independent.
00:15
I did my best recreating this table.
00:18
Double check the values that they match up with your values.
00:22
It's really difficult to read this.
00:25
I looked at some different examples and i think i have the right information based on.
00:31
Off of what i'm seeing.
00:34
But again, double check against your numbers before moving ahead with submitting any work for this one.
00:43
So you may have to, if i misread this table, you may have to swap out some numbers.
00:48
But route a is 25%.
00:53
Route b is 75%.
00:57
And this is the part that's a little bit tricky to read, but i think i'm reading it as server 1 is 0 .01, server 2 is 0 .007.
01:08
Server 3 and server 4 are zeros for route a.
01:11
For route b, server 1 was a 0, server 2 was a 0, server 3 was 0 .005, and server 4 is 0 .008.
01:22
So the first thing we're asked to do is to draw a probability tree.
01:26
So we're going to start by doing route a and then route b...
