On the info you've given its 100%... you've defined the distribution to be between 75 and 105. I'm guessing there's a typo somewhere....
Just for anoyone looking though, if the disribution of oil price in 5 years was cont. uniform between 75 and 105, probability opf the price being less than 80 would be, the area under the curve between 80 and 75:
(80-75) / 105 - 75
=5/30
=16.67% |
