You are playing a wizard game where you roll a dice three times to collect magical artefacts. Each time you roll the dice, you collect an artefact according to these rules: If you get a 2 or a 4, you collect a book of spells. If you get an odd number, you collect an enchanted coin. If you get a 6, you collect a wand. Let X be the number of books you collect. Find the probability distribution for X and give the following probabilities to 3 decimal places: a) P(0): Answer b) P(1): Answer c) P(2): Answer d) P(3): Answer
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.
