A local public-action group solicits donations by telephone. For a particular list of prospects, it was estimated that for any individual the probability was 0.05 of an immediate donation by credit card, 0.29 of no immediate donation but a request for further information through the mail, and 0.66 of no expression of interest. Information is mailed to all people requesting it, and it is estimated that 30% of these people will eventually donate. An operator makes a sequence of calls, the outcomes of which can be assumed to be independent. What is the probability that the first call leading to any donation (either immediately or eventually after a mailing) is preceded by at least five calls that never lead to a donation? (Round to three decimal places as needed)

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.
