A group of people were asked if life exists elsewhere in the galaxy. 270 responded "yes", and 478 responded "no". Find the probability that if a person is chosen at random, he does NOT believes life exists elsewhere in the galaxy. 374 Probability = (Please enter a reduced fraction.) %3D 239
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.
Probability= n(E)/n(S)
Where
n(E)= number of possible events
n(S) = total number of possibilities.
