Final answer:
The student is asking about a probability calculator for different types of events: binomial, Poisson, normal, and exponential.
Step-by-step explanation:
The student is asking about a probability calculator for different types of events: A) Binomial Probability, B) Poisson Probability, C) Normal Distribution, and D) Exponential Distribution.
The binomial distribution is used when there are only two possible outcomes, such as success and failure, and the number of trials is fixed. The Poisson distribution is used to calculate the probability of a number of events occurring in a fixed interval of time or space, given an average rate of events. The normal distribution is used to model continuous random variables with a symmetrical bell-shaped curve. The exponential distribution is used to model the time between events that occur at a constant average rate.
