jar contains 20 identical ping-pong balls except that 4 are red, 5 are yellow, 4 are blue, & 7 are green. Five balls are removed from the jar at random and without replacement. Find each:
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.
A jar contains 20 identical ping-pong balls except that 4 are red, 5 are yellow, 4 are blue, & 7 are green. Five balls are removed from the jar at random and without replacement.
Find each:
