he credit card department of a certain bank knows from experience that 5% of the cardholders have some high school, 15% have completed high school, 55% have had some university and 25% have completed university. Of the 500 cardholders whose cards have been called in for failure to pay their charges this month, 50 had some high school, 100 had completed high school, 160 had some university, and 190 had completed university. Can we conclude at a 1% level of significance that the distribution cardholders who do not pay their charges is different from all others
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.
