This problem aims to familiarize us with the probability density functions. The concepts required to solve this problem are continuous random variables and probability distributions, which include exponential distribution and densities of random variables. A probability density function or PDF is used in probability theory to describe the probability of a random variable staying within […]

The main objective of this question is to find the number of calls in order to get a donation of 100 dollars from these calls. This question uses the concept of Binomial probability. In binomial distribution, we have two possible outcomes for a trial, which is success or failure. Expert Answer Read moreIn how many […]

This question aims to find the linear correlation between different indicator points on the XY-axis. The coefficient of linear correlation indicators analyzes the strength of the linear relationship between different variables. The correlation is called positive if the linear coefficient is greater than zero, and it is called negative if the linear coefficient is greater […]

The probability density function f(x) of a random variable x is given below, where x is the lifetime of a certain type of electronic device (measured in hours): [ f(x) =Bigg{begin{array}{rr} dfrac{10}{x^2} & x>10\ 0 & xleq 10 \ end{array}] Read moreIn how many different orders can five runners finish a race if no ties […]
