A developer for another mobile game uses gems to help players advance faster. They are going to select a player at random to win 100 gems. From statistics the developer has collected, they know P(scored at least 500 points) = 0.3 and P(already bought gems | scored at least 500 points) = 0.05. What is the probability that the winner will have both scored at least 500 points and bought gems? Explain or show your reasoning
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
