Suppose there are 87 red balls and 86 yellow balls in a box. Two balls are drawn from the box without replacement. What is the probability that both balls selected is yellow?
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.
Suppose there are 87 red balls and 86 yellow balls in a box. Two balls are drawn from the box without replacement. What is the
Probability:
Probability of an event is the number of outcomes favorable to the event, divided by the total number of possible outcomes in the study.
Suppose the event of interest is A. If the number of cases favorable to the event A is n (A) and the total number of all possible cases in n, then the probability of A is given as:
P (A) = n (A) / n.
