A box contains 4 red, 7 white and 9 blue marbles. You reach in and remove two marbles one at a time without replacement. What is the probability that: a) the first marble is blue and the second marble is red? b) the first marble red and the second marble is white? c) both marbles are the same color?
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 box contains 4 red, 7 white and 9 blue marbles. You reach in and remove two marbles one at a time without
replacement. What is the probability that:
a) the first marble is blue and the second marble is red?
b) the first marble red and the second marble is white?
c) both marbles are the same color?
