Problems in Probability (Problem Books in Mathematics)

It offers high school and college students an excellent mathematics workbook of rigorous problems that will assist in developing and cultivating their logic and probability skills. These 20 sets of intriguing problems test originality and insight rather than routine competence. They involve theorizing and verifying mathematical facts; examining the results of general statements; discovering that highly plausible conjectures can be incorrect; solving sequences of subproblems to reveal theory construction; and recognizing "red herrings," in which obvious relationships among the data prove irrelevant to solutions.

Hints for each problem appear in a separate section, and a final section features solutions that outline the appropriate procedures. Ideal for teachers seeking challenging practice math problems for their gifted students, this book will also help students prepare for mathematics, science, and engineering programs. Mathematics buffs of all ages will also find it a source of captivating challenges. Fifty Challenging Problems in Probability with Solutions.

Examples of events can be: Tossing a coin with the head up Drawing a red pen from a pack of different coloured pens Drawing a card from a deck of 52 cards etc. An event that occurs for sure is called a Certain event and its probability is 1.

This means that all other possibilities of an event occurrence lie between 0 and 1. This is depicted as follows: This also means that a probability value can never be negative. Every event will have a set of possible outcomes. Consider the example of tossing a coin.

So is the probability of tail. Basic formula of probability As you might know from the list of GMAT maths formulas , the Probability of the occurrence of an event A is defined as: What is the probability of rolling a 5 when a die is rolled? Compound probability Compound probability is when the problem statement asks for the likelihood of the occurrence of more than one outcome. P A or B is the probability of the occurrence of atleast one of the events. P A and B is the probability of the occurrence of both A and B at the same time.

Mutually exclusive events are those where the occurrence of one indicates the non-occurrence of the other OR When two events cannot occur at the same time, they are considered mutually exclusive. Consider the aforementioned example of drawing a pen from a pack, with a slight difference.
