So for these crushes when you use a table in the exercise.
00:07
15.
00:08
So let's go back to the exercise.
00:10
15 to see the table pull this table.
00:13
We have, ah, six rows and six columns pull.
00:18
It shows it will present a different country there.
00:22
China, france, india.
00:23
You can you, us and who will call? um, it's represent the front education, apple, postgraduate colleagues, high school point or glass and no answer.
00:34
And they also has, uh i'm total colin one total rose.
00:40
And we know that the total number of the table is 76 night there will and the then let's go back to the questions.
00:51
The question is a probable thing that a person from the united states has done pro posed too great.
00:58
I started.
00:59
Ah, hey, i asked him probably that person from united states and did graduate postgraduate study.
01:10
I read g.
01:13
Yet what? what we we need to do is go back to the table and find you asked rose and the postgraduate columns and find in section.
01:24
The number is 84 so the probability here is it goes to a holding by by its total on birth 76 nights they will get approximately because through their point, they want it.
01:42
And the problem be iss probable that he that ah, a person from united states who have don't gradual proposed a graduate story.
01:55
So here, as different from problem a sense, it's a conditional probability.
02:01
And it's a probability that the person from the united states, uh, given that he has already don't postgraduate study.
02:14
But here was you use ah, conditional for look, cackle i this it goes to p your ass and a postgraduate study divide by the postgraduates...

This answer is a bit confusing It would benefit from clearer explanations and organized steps for each part of the question. 🤔

the answer seems to be trying to calculate probabilities, but it's hard to follow. the explanation is all over the place. 🌪️

can someone break down the steps for each part of the question? it's tough to follow the explanation from the video. 😕

The video answer is all over the place, making it hard to understand the solution to each part of the question! It needs more structure and clarity! 🙄

Its useful that the answer attempts to tackle the probabilities in the question but the explanation needs to be organized and simplified. 📊
