An urn contains 7 yellow chips, 4 white chips, and 10 green chips. Four chips are to be selected one at a time and without replacement (wtr). a. Find the probability that exactly two of the four chips selected are green.b. Find the probability that exactly two yellow and two white chips are drawn.
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.
