Two tetrahedral dice, each with faces labelled 1, 2, 3 and 4, are thrown and the random variable X represents the sum of the numbers shown on the dice. The table shows the probability for each possible sum of the numbers X: 2 3 5 6 78 1 Р(X) 16 2 3 4 3 2 1 16 16 16 16 16 16 (a) Is this a probability distribution? Explain briefly. (b) What is the probability that any throw of the dice results in a value of X which is an odd number? (b) (c) Find the mean of the probability distribution. 4)

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.
