Consider the following joint probability table. B1 B2 B3 B4 A 0.11 0.09 0.11 0.18 Ac 0.12 0.18 0.11 0.10 1. Given that B2 has occurred, what is the probability that A occurs? (Round intermediate calculations to at least 4 decimal places and final answer to 4 decimal places.) 2. Given that A has occurred, what is the probability that B4 occurs? (Round intermediate calculations to at least 4 decimal places and final answer to 4 decimal places.)
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.
Consider the following joint probability table.
| B1 | B2 | B3 | B4 | |
| A | 0.11 | 0.09 | 0.11 | 0.18 |
| Ac | 0.12 | 0.18 | 0.11 | 0.10 |
1. Given that B2 has occurred, what is the probability that A occurs? (Round intermediate calculations to at least 4 decimal places and final answer to 4 decimal places.)
2. Given that A has occurred, what is the probability that B4 occurs? (Round intermediate calculations to at least 4 decimal places and final answer to 4 decimal places.)
