Your oil exploration crew is testing for well sites. Historically, the probability of finding oil in your particular geographical region is 1/20. Your company's headquarters needs your crew to locate 2 oil-producing wells within 2 weeks. If set-up and testing for oil takes 1 day, what is the probability that it will take no more than 2 working weeks (including weekend days) to find these 2 spots? What probability distribution did you use to solve this problem?
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

What probability distribution did you use to solve this problem?
Given,
P(finding oil in your geographical region)=P(getting a success)=p=1/20 q=19/20
number of oil fields to spot= number of success=r=2
Let X be the total number of days required to spot 2 oil fields.
