    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.

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

    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?

      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.

      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.

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

    • @matemaatika-math
      @matemaatika-math 4 роки тому +1

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

      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...

      I think that you miscalculated the first solution.
