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? Select one: O a.0.10 O b.o.03 C.0.30 O d.o.97

Expert Solution
Step 1
It is given that the study conducted on 20 different locations. The possibility of a location to truly have an oil field is 30%.
Step 2
Let the random variable X is the number of locations truly have oil field.
The random variable X follows Binomial distribution with n as 20 and p as 0.30.
Calculations:
Calculate the probability that at least 3 locations will truly have oil fields is as follows:
Therefore, the probability that at least 3 locations will truly have oil fields is 0.97.
