Probability Density Functions (6 of 7: Unbounded integrals)

[@ethoszone5652]

Hi mate. I'm a 38 year old and loving watching you. Can I ask if you have any suggestion where to begin with my 3 yo son with math? I'm terrible at math! So really would love start him young :) thank you for what you have done. It's amazing.

No he isn’t he just loves to watch Eddie woo

go to khanacademy

Start with the integration of the Gaussian function

[@putrawahyudi4825]

Thanks for your explanation..

[@freddyvejen743]

lim f(x -> infinity) = 0 , but lim F(x -> infinity) = 1

Hi Mr Woo I love math and everyone of my friends say why do you love math and i can just see the fun and the excitment in math and honsetly i look up to you i see you nearly every day but always too scared to come up annd say hi

If the two ways give the same answer, then 0 - F(65) = 1 - F(65) + F(50) or F(50) = -1 How is this possible?

[@nicolasanese6499]

It is possible because it is the value of an ANTIDERIVATIVE of a Probability Density Funtion, it's NOT the value of a Probability Density Function itself.

[@tavishu]

Nicolas Anese Even if it is the anti-derivative, how can it be negative? That would imply that the probability density function itself is negative on some domain.

@@nicolasanese6499 The antiderivative of the PDF is essentialy the cummulative function, which should approach 1 as x goes to infinity. There is also a big issue, because in continuous random variables we should not have P(X=x) because it would always be 0.

Sir do you read these comments.?

[@abrarshaikh7592]

Why any number to power 0 is equals to 1 @eddie woo

[@matemaatika-math]

Because 1 === a ^ b / a ^ b === a ^ (b - b) === a ^ 0.

[@livlucia11]

thats just a rule in maths, I'm not sure the explanation but just know anything to the power of 0 is equal to 1

6 ÷ 2(2+1) = 1 6 ÷ 2(2+1) = 9 What do you think...

[@matemaatika-math]

I think that you miscalculated the first solution.
