A progressive college experiments with matching roommates at random, regardless of gender or how cool that person is (or you are). Suppose the joint distribution of gender and coolness is: +----------------------------+ | Cool Lame | |----------------------------| | Boy .0652174 .4728261 | | Girl .0108696 .451087 | +----------------------------+ You hear that your roommate 'Ali' is a girl. Knowing this, what is the probability that 'Ali' is Cool? (Enter your answer to three decimal places: ex: 0.123)
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.
