@eriknelson2559 4 года назад

For question 5, parts d&e, you get the "central region probability" of 1 - (1-q^n) - q^N = q^n - q^N where N>n such that the probability is positive definite

@oskarwallberg4566 Год назад

Exactly, P(a _< X _< b) = P(X _< b) - P(X _< a-1) = 1-q^b - (1-q^(a-1)) = q^(a-1) - q^b If X can be equal to "a" then you have to subtract 1 to only remove probability of outcomes before "a". but... P(a < X _< b) = P(X _< b) - P(X _< a) = 1-q^b - (1-q^a) = q^a - q^b

@kamran_desu 2 года назад

Great lesson, only concern is that we're representing Geometric as a continuous curve though it should be discrete. Another approach for (c) and (d) using cumulative approach: (c) P(X

@akash14890 Год назад

Yes,I a just thinking about that and realize something is wrong, In the video I don't understand the process but the cumulative process is good I think.

can you do a video on negative binomial distribution? there are no good tutorials

@harshit8807 4 года назад

your explanation is great. But I have a doubt in 3 rd question. It is mentioned that every 10th person is a teacher but it is not mentioned anywhere that first 9 person are not teachers

@ninalazaridou6462 Год назад

I thought the same thing. If we don't care what the first 9 people are, then since encountering one person is an independent event, the probability that the 10th person we meet is a teacher is just 4%.

How to differentiate between geometric distribution questions and binomial distribution questions?

@aryan_kenya 3 года назад

I've gain alot from this video,thank you so much...kindly do for me this question. Identical independent trials are carried out .The probability of successful outcome is P.On average five trials are required until a successful outcome occur. Find,(i) P (ii) the probability that you succeed for the first time in the fifth trial.

@Joe-un1tl 3 года назад

I know I'm late but after trying this problem for myself I got P=1/5 and the probability that you succeed for the first time in the fifth trial as 8.2%. Not 100% sure though.

#3(a) should be just straight probability, not the formula. In the first two, the question was about the xth event being the first success, whereas in #3 the question is about the xth event simply being a success independent of the earlier samples.

@beckyzhao4129 4 года назад

23:50 you tried to get P(X > = 18), and stated that P(X>=18) = P(X >17) . This is a continuous distribution, so didn't you ignore that P(X>=18) should not include P( 17

@yaweli2968 2 года назад

You will probably think P(X>=18) should be P(X>=17.5) in the normal case with a correction factor, but the geometric is not continuous so it makes sense when you drop the “=“.

@abdullahsafi7894 4 года назад

Thanks for this amazing video. but I have a question, in Q3, why did you assume that the first 9 people I counted must not have any teacher!?

@lifeinvestments3954 3 года назад

That was my concern but I think it's just a minor mistake

@Keithustus 3 года назад

Same mistake in 4(a) too. That’s when I stopped watching this crap.

@yaweli2968 2 года назад

@@lifeinvestments3954 : it’s not a minor mistake. Each random variable describes a particular event. Geometric r.v count the number of trials needed to get the first success or the number of failures needed to get the first success. Note here that, the first success is running into the first teacher to be the 10th person we meet. Or you meet 9 people and they are all not teachers, then you finally meet the 10th person who is a teacher. Understand what r.v the video is about and it’s properties before you confuse yourself,
