On hot, sunny, summer days, Jane rents inner tubes by the river that runs through her town. Based on her past experience, she has assigned the following probability distribution to the number of tubes she will rent on a randomly selected day. x 25 50 75 100 Total P(x) .11 .33 .27 .29 1.00 (a) Find the probability expressions: (Round your answers to 2 decimal places.) a. P(X = 25) b. P(X ≤ 50) c. P(X > 25) d. P(X < 75)
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.
On hot, sunny, summer days, Jane rents inner tubes by the river that runs through her town. Based on her past experience, she has assigned the following probability distribution to the number of tubes she will rent on a randomly selected day.
| x | 25 | 50 | 75 | 100 | Total |
| P(x) | .11 | .33 | .27 | .29 | 1.00 |
(a) Find the probability expressions: (Round your answers to 2 decimal places.)
| a. | P(X = 25) | |
| b. | P(X ≤ 50) | |
| c. | P(X > 25) | |
| d. | P(X < 75) |
