bag of marbles contains 4 red, 3 blue, 2 green and 1 yellow marble. Half of the red and green marbles are glass, and all of the other marbles are polished stone. What is the probability of selecting: Add the colors together to determine how many marbles are in the bag. This will become the right side of the answer. Determine how many marbles exactly fit the specified criteria to find the left side. Remember to reduce if necessary. A yellow stone marble: Ratio: ____ : ____ A blue or green stone marble: Ratio: _____ : _____ Two red marbles in a row without replacement: Ratio: _____ : _____ Three glass marbles in a row with replacement: Ratio: _____ : _____
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.
