Explain why there must be a mistake in each of thefollowing statements: (a) The probability that Jean will pass the bar examina-tion is 0.66 and the probability that she will not pass is −0.34.(b) The probability that the home team will win anupcoming football game is 0.77, the probability that it willtie the game is 0.08, and the probability that it will win ortie the game is 0.95.(c) The probabilities that a secretary will make 0, 1, 2, 3, 4,or 5 or more mistakes in typing a report are, respectively,0.12, 0.25, 0.36, 0.14, 0.09, and 0.07.(d) The probabilities that a bank will get 0, 1, 2, or 3 ormore bad checks on any given day are, respectively, 0.08,0.21, 0.29, and 0.40.
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.
Tree diagram
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.
following statements:
tion is 0.66 and the probability that she will not pass is
(b) The probability that the home team will win an
upcoming football game is 0.77, the probability that it will
tie the game is 0.08, and the probability that it will win or
tie the game is 0.95.
(c) The probabilities that a secretary will make 0, 1, 2, 3, 4,
or 5 or more mistakes in typing a report are, respectively,
0.12, 0.25, 0.36, 0.14, 0.09, and 0.07.
(d) The probabilities that a bank will get 0, 1, 2, or 3 or
more bad checks on any given day are, respectively, 0.08,
0.21, 0.29, and 0.40.
