A tech distribution store sells 64-megapixel and 128-megapixel cameras. This store received a shipment of 15 of these cameras, of which three have a resolution of 64 megapixels. Suppose that 5 of these cameras are chosen to be placed on the counter, the others are placed in the cellar. Let X be the number of 64 megapixel cameras, among the five chosen to store them on the counter. The probability that X = 2 is: a) 0.021978 b) 0.978021 c) 0.780219 d) 0.219780
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.
