ndividuals with multiple sclerosis were classified according to the presence or absence of brain lesions, and the onset of the condition (Early, Mid, Late). The probabilities of these are shown in this two-way contingency table: Early Mid Late Lesions 0.015 0.324 0.441 Not 0.171 0.036 0.013 One of these individuals is selected at random. Find the probability that the onset of the condition was either Mid or Late
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.
Individuals with multiple sclerosis were classified according to the presence or absence of brain lesions, and the onset of the condition (Early, Mid, Late). The probabilities of these are shown in this two-way
| Early | Mid | Late | |
| Lesions | 0.015 | 0.324 | 0.441 |
| Not | 0.171 | 0.036 | 0.013 |
One of these individuals is selected at random. Find the probability that the onset of the condition was either Mid or Late. (Enter your answer as a decimal rounded to 3 digits.)
