Exploration studies are conducted in 20 different locations seeking oil fields in Oman. From a retrospective study it has been found that the possibility of a location to truly have an oil field is 30%. This low probability is due to the complexity of the geological conditions and their challenges in Oman. As a result, the chance to invest in exploration and getting no oil fields is 70%. Determine the probability that at least 3 locations will truly have oil fields?
