Ah, maybe that's because you're very genius. ;) And not everybody is on your level? :)
I didn't take stats... Maybe Ari, DK or others may be able to help.. :)

Lol. Good attempt. :P
But am not mistake-proof. ;)
It's okay... I'll wait, hopefully they notice it.
Nevertheless, thank you. :)

Did you do the normal distribution part ?

Did you do the normal distribution part ?
Yes, I did everything. But I think you should subtract the prob you get from 1.
"probability that it runs out of fuel before it has travelled 367 km"
Using the normal dist. you'll get the probability that it can travel 376 km on 20 litres of fuel, nah?

Nah.
If your car has an average of 20 and you want it to run 80, it is just not possible. Think logically. It was not stated less than 367 km, it WAS before 367 km.

Yes, less than 367. Had already made provisions.
I was thinking about it while going to tuitions. ::)
My teacher told me "Alphaaaa, I'll kill you!" :P
Thank you Fidato. :)

In India, it's common in common to get to tutions. When it is the time, mothers tell, GET OUTTA HERE. Don't you see it's tution time. ::)
But, I do not take tutions.
