Appreciate your efforts Sir...You are a good samaritan indeed...God Bless you...Respect from India...

[MrAnestay]

Thank you! very intuitive explanations. Which i desperately needed after not studying stats for 4 years

[cleow]

Why is F(100) = 1 if the discrete distribution only have up to P(X=6) as a possibility within the probability function? (8:41)

[caller]

@3:20 how come the return you make is an infinite decimals when 20.19 - 20.07 = 0.12 ?

[jbo]

Salute! Your explanation makes it much easier to understand

[chinmayakhuntia]

Nice explanation sir but the NCR in 23:53 =252 not 25, thank you. your videos helps me a lot😍🙏

[craigdoyle]

has anyone calculated nCx (nCr) on the HP 12c?

As a side note, thank you IFT - especially the presenter - very thorough lectures.

[pranaykothari]

how did you get 10C5 as 25 I am getting it as 252.

[mphoboemotshwaane]

hello, how do i get 10C7 in a calculator?

[avinashpadhi]

Hello sir! Please let me know if binomial tree is coming in our exam or not, bcoz i couldn't find on your videos.
I hope you'll reply soon

Why probability of success is taken 0.50 in solved question.

[abhikool]

In the explanation for the Probability distribution of Binomial Random Variable’s Formula, you say that order doesn’t matter but I think that’s INCORRECT.

Since, we are already using nCx in the formula. nCx can be interpreted as choosing 7 out of 10 positions where we will obtain success and in the remaining places we have failure. Please let me know your thoughts on this!!!!

[danielayeh]

Hay nice job but if 7 successes out of 10 trials, then 3 failures will occurs so the probability will not be 0.5 for success and 0.5 for failure. Rather 0.7 for success and 0.3 for failure
