In a campus restaurant it was found that 35% of all customers order vegetarian meals and that 50% of all customers are students. Further, 25% of all customers who are students order vegetarian meals.a. What is the probability that a randomly chosen customer both is a student and orders a vegetarian meal?b. If a randomly chosen customer orders a vegetarian meal, what is the probability that the customer is a student?c. What is the probability that a randomly chosen customer both does not order a vegetarian meal and is not a student?d. Are the events “customer orders a vegetarian meal” and “customer is a student” independent?e. Are the events “customer orders a vegetarian meal” and “customer is a student” mutually exclusive?f. Are the events “customer orders a vegetarian meal” and “customer is a student” collectively exhaustive?
Compound Probability
Compound probability can be defined as the probability of the two events which are independent. It can be defined as the multiplication of the probability of two events that are not dependent.

Probability theory is a branch of mathematics that deals with the subject of probability. Although there are many different concepts of probability, probability theory expresses the definition mathematically through a series of axioms. Usually, these axioms express probability in terms of a probability space, which assigns a measure with values ranging from 0 to 1 to a set of outcomes known as the sample space. An event is a subset of these outcomes that is described.
Conditional Probability
By definition, the term probability is expressed as a part of mathematics where the chance of an event that may either occur or not is evaluated and expressed in numerical terms. The range of the value within which probability can be expressed is between 0 and 1. The higher the chance of an event occurring, the closer is its value to be 1. If the probability of an event is 1, it means that the event will happen under all considered circumstances. Similarly, if the probability is exactly 0, then no matter the situation, the event will never occur.
