Answer 2

In probability theory, Gaussian Distribution or normal distribution is used for continuous Random variables. Rayleigh distribution is a continuous probability distribution and used for non-negative variables. Also, Exponential distribution is a continuous distribution and is used to find the events.

Then the above three distributions are used for a continuous random variable. Therefore, the remaining option (b) Poisson Distribution is the correct one and it is used for discrete random variables.
