Assume that 12 jurors are randomly selected from a population in which 73% of the people are Mexican-Americans. Refer to the probability distribution table below and find the indicated probabilities. xx P(x)P(x) 0 0+ 1 0+ 2 0.0001 3 0.0007 4 0.004 5 0.0172 6 0.0542 7 0.1255 8 0.2122 9 0.2549 10 0.2068 11 0.1016 12 0.0229 Find the probability of exactly 5 Mexican-Americans among 12 jurors. P(x=5)=P(x=5)= Find the probability of 5 or fewer Mexican-Americans among 12 jurors. P(x≤5)=
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.
