A petroleum engineer estimated the chances of drilling a dry well to be around 50% , and chances of obtaining a well contains 40 to 100 MM bbls of oil to be around 40 % and 10 % chance of obtaining a reserve between 100 and 160 MM bbls. Calculate the mean , variance and standard deviation of this data system ? The lowest value of permeability in a given well is 10 md , the most probable is 50 md and highest value is 100 md. Estimate the probability that the permeability will be less than 30 md? And the probability that the permeability is less than 80 md?
