In drilling a vertical wellbore, the spacing between major fractures are recorded. It has been found that this spacing is having a mean of 1800 ft anda variance of 3,240.000 ft Estimate the probability that there are no major fractures in the first 3000 ft of drilling and at a depth of 4000- S000 ft?
