he life of a power expanentially disoributed with mean life of 25 years. IF three trowers operated independently transmission tower is being erected what is the probability that at Still Stand after 3s years? axe e A at the same time, least 2 ill years?
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.
Given that the random variable X as the life of a power transmission tower follows Exponential distribution with a mean lifetime of 25 years.
The probability density function for X is,
Consider, the probability that it will standard after 35 years is,
