n a certain town, citizens' groups have identified three intersections as potentially dangerous. They collected the following data. Intersections A B C Number of vehicles /day 25,500 3,890 8,580 Number of vehicles in accidents /year 172 55 138 For each intersection, find the probability Pr(n) that a vehicle entering the intersection will be involved in an accident. (Use 365 days per year. Round your answers to seven decimal places.)
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.
In a certain town, citizens' groups have identified three intersections as potentially dangerous. They collected the following data.
| Intersections | |||
|---|---|---|---|
| A | B | C | |
| Number of vehicles /day |
25,500 | 3,890 | 8,580 |
| Number of vehicles in accidents /year |
172 | 55 | 138 |
For each intersection, find the probability Pr(n) that a vehicle entering the intersection will be involved in an accident. (Use 365 days per year. Round your answers to seven decimal places.)
