Suppose that 3 out of every 5 drivers come to a complete stop at an intersection having flashing red lights in all directions when no other cars are visible. 15 drivers coming to an intersection under these conditions will be randomly selected. Let Y be the count of these selected drivers that come to a complete stop. Use the binomial excel spreadsheet to help you find the following. P(Y=8) = A) 0.1331 B) 0.1771 C) 0.1551 D) 0.1991 P(Y≤8) = A) 0.3788 B) 0.4186 C) 0.3902 D) 0.4336 P(Y≥8) = A) 0.7869 B) 0.7291 C) 0.7536 D) 0.6769
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.
