A collection of marbles is listed below: 1 marble labeled with the number 1 2 marbles labeled with the number 2 3 marbles labeled with the number 3 4 marbles labeled with the number 4 All marbles are placed in a box, and one marble is selected at random from the box. Let x be the random variable that gives the label in the selected marble. a) Construct a probability distribution for this random variable.
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.
A collection of marbles is listed below:
- 1 marble labeled with the number 1
- 2 marbles labeled with the number 2
- 3 marbles labeled with the number 3
- 4 marbles labeled with the number 4
All marbles are placed in a box, and one marble is selected at random from the box.
Let x be the random variable that gives the label in the selected marble.
