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.

My teacher told me "Alphaaaa, I'll kill you!" :P
Thank you Fidato. :)
