Out of any 30 car accidents, authorities are analysing the likelihood that different numbers were caused by texting and driving. A study suggests that 1 in 4 accidents are caused by texting and driving. Calculate the following: a) The probability that 10 or more of the accidents are caused by texting and driving. b) The probability that between 8 and 10, including 8 and 10, accidents are caused by texting and driving. c) The expected number, of the 30 accidents, that are caused by texting and driving.
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.
