8) Jun buys a mega million every week until he wins the top prize. Successive purchases are independent of each other and the probability of winning the top prize is approximately one in hundreds of millions. Let X be the number of lotteries Jun purchases until he wins a mega million. Does X follows a binomial setting? A. No, because the outcome is not binary. B. No, because the number of trials is not fixed. C. Yes, because each trial is independent. D. Yes, because each trial has the same probability. E. No, because the probability would change
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.

Let X be the number of lotteries Jun purchases until he wins a mega million. Does X follows a binomial setting?
| A. |
No, because the outcome is not binary. |

| B. |
No, because the number of trials is not fixed. |
|
| C. |
Yes, because each trial is independent. |
|
| D. |
Yes, because each trial has the same probability. |

| E. |
No, because the probability would change |
We use binomial setting when the each trial of an experiment is mutually exclusive and complementary.
It has finite no. of trials and each trial is independent of each other.
