Ms Greenaway sells mangoes at a roundabout in her town. On any given day, the probability of Ms Greenaway selling 0 mangoes is 0.1, the probability of Ms Greenaway selling 1 mango is 0.7 and the probability of Ms Greenaway selling 2 mangoes is 0.2. (a) Construct the probability distribution table for Ms Greenaway’s mango sales. (b) Calculate Ms Greenaway’s expected daily mango sales and the standard deviation of Ms Greenaway’s daily mango sales.
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.
