Addition Rule in Probability

The addition rule in probability deals with finding the probability of the union of two or more events. In simpler terms, it helps us calculate the probability of either event A happening, event B happening, or both occurring.For two events A and B, the addition rule...
Suppose the diameter of aerosol particles in a particular application is uniformly distributed between 2 and 6 nanometers. Find the probability that a randomly measured particle has diameter greater than 3 nanometers.

Suppose the diameter of aerosol particles in a particular application is uniformly distributed between 2 and 6 nanometers. Find the probability that a randomly measured particle has diameter greater than 3 nanometers.

In this problem, the diameter of the aerosol particles is a continuous random variable that is uniformly distributed between 2 and 6 nanometers. This means that all values between 2 and 6 are equally likely. In this situation, our Random Variable X is a Uniform...
