to find the probability that exactly 3 of the 6 dentists prefer MintyFresh toothpaste. (a) First fill in the details of the binomial probability formula: Write all proportions to 4 decimal places. P(3)=P(3)= (( )) ( ) ( ) (b) The probability, accurate to 4 decimal places, is
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.
According to a Gallup poll, 71% of American adults prefer saving 2 out of 6 dentists prefer MintyFresh toothpaste. Suppose 6 dentists are randomly chosen. Use the formula for binomial probabilities
to find the
