Census data shows that 30% of residents of Squirfornal County are black. A pool of potential jurors is to be selected for a trial. Names of Squirfornal County residents are drawn one by one to make up the pool of potential jurors. the first twelve whose names were drawn are seated and interviewed to see if they would be appropriate for the jury. find the probability that this group of 12 potential jurors contains... HINT: the selection of each juror can be considered a Bernoulli trial which is a 'success' if the potential juror is black g) what is the expected number of black potential jurors h) if X = the number of potential jurors who are black, find o, the standard deviation for X
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.
