This question first we need to compute what is the probability here that like we have weights in this case they are like under 200 so this is the first probability that we want to compute so this here basically using the table we should check like how many people we have like in this category weight that is like under 200 so the total number of people they are in this category is 9.
00:40
And we should divide this by the total number of people that we have, 69 observations.
00:46
So this is 11304.
00:50
Now, for the other, we should compute like now.
00:56
What is the probability that we have a rocky? and given that the weight, or the weight, is under 200.
01:11
So given that this is happening, this means that i should fix the row that has like weight under 200.
01:21
So we have like nine.
01:22
So i'm fixing that we're in that row.
01:24
So nine.
01:25
That's right that i'm putting the total number of people as nine.
01:29
And then i should check how many are rocky in this category...
