I know it's been a long time since you posted but to clarify he used .5 since all those values used for years are the integer 1,2,...n. Therefore .5 = 6 months
one minor comment - the probability of a shark attack between year 2 and year 4r is NOT 11%. This is the probability that the next shark attack (from now), will occur in that interval. T
Little late lol, but when you define a pdf, you define it as a piecewise, like X = e^x, 1 < x < 2 and then 0 otherwise. So when you take the limit of -infinity you get 0 because of how you define the pdf.
You're the man! Thanks for the very straightforward explanation.
Very helpful presentation. It makes reading a little more easy. Thanks. Jackson
you are amazing man. please make more videos . you saved my from giving up my stats course . thanks you so much. more videos please . thanks so much
An outstanding explanation for CDF an PDF
Excellent ! Love it ...good job mate !!! very helpful my professor can't explain it as good as you
Thank you so much! These videos helped me a lot
this is great.
one observation: on the last part i think there' s a type = it should be (to the 6th power) instead of 5 (to the 5th power?)

Very useful thanks
great video. I never write rate or post anything on youtube but I couldn't help myself
Very helpful, thank you.
Cheers this was really helpful.
You draw a brace (them big bracket thingys like that { ) then write the inequalities and the cdf
how do you lay it out after you get the cdf. Like how do you write the cdf.
wow crystal clear. amazing! ty!
Am I the only one getting 39.3% for P(X
me too but the video is comprehensive
+John Griffin Yeah, i'm also getting that. The explanation is good though.

can someone explain the limits of integration used here...

why does he just assume the rate of shark attacks is once per year?
This is just an example, he could have some data which provided that probability density function
I could read it in a book) could you explain more simpler?))
for more clear i would have to charge... .

Six years on and this statement still holds true! 🤣
