I am getting jealous 😭 because teachers in my college don't teach like you. they just give a formula and say solve this😭😭.thanks for teaching this 🙏🙏👍👍
Can u plz tell me what ............. If random variable X takes the values 1, 2, 3 and 4 such that 2P(X=1) =3P(X=2) =P(X=3) =5P(X=4), Find the probability density function and cumulative density function of X?
Thank You Anil Kumar for this wonderful presentation I have understood it fully. If I have a question I would like to be assisted also in the probability density function how can I reach you so that you solve it and present it here on your channel?
Anil Kumar thank you so much it's really helpful. But I have a question around the final answer. How come is that possible to have 55/32. when I did the calculation it didn't work. thank you
Thanks for the explanation Sir.. I have small question in this video while finding the value of k as you explained (k-x/4)dx = kx -x**2/2 * 4 -- why we multiplied 2 with 4... how we get 2 here? could anyone can answer me please?
That was a mistake, actually the square only applies to 2.5 but sir forgot to put brackets for x*2 so the square is also applied to 8. do the calculation on your own you'll get the answer.
Thanks for bringing my attention to this part. I should have included the area of rectangle below the triangle. Area of triangle 2(.5)/2 + Area of rectangle (2 * 0.5) = 1. Thanks
@@MathematicsTutor , again there is an error in what you wrote Area of triangle 2(.5)/2 + Area of rectangle (2 * (1/4))=1 Whatever you wrote will sum it up to 1.5
@Anil Kumar Sir - Could you please help me solving the below problem? Or anyone who could help me solving below problem will be much appreciated. Thanks. A continuous random variable X has a probability density function f(x) = 3 (xpower3), 0
The 40% of students failed an end of semester exam. The mean for the test was 110 and the standard deviation was 22. What was the passing score? please solve this for me
What, you so first in your explanation, tell us where this has come from because someone just opens and because they've not understood where the values you substituting has come from, they just close the video. Next time explain how you substituting your variables in your equations
