Suppose that a box contains 5 RED blocks, 4 BLUE blocks, and 3 GREEN blocks. Suppose that 6 are drawn one after another without replacement. What is the PROBABILITY that exactly 3 are RED?
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 that a box contains 5 RED blocks, 4 BLUE blocks, and 3 GREEN blocks. Suppose that 6 are drawn one after another without replacement. What is the
It is given that the box contains 5 RED blocks, 4 BLUE blocks, and 3 GREEN blocks.
We are drawing 6 blocks one after another without replacement and we have to find the probability that exactly 3 are RED. It means that other 3 maybe BLUE or GREEN.
Total number of red blocks=5
Total no. of BLUE+GREEN blocks= 4+3=7
Total number of blocks in the box= 5+4+3=12
