Basic Concepts Probability theory was invented in the 17th century by two French mathematicians, Blaise Pascal and Pierre de Fermat, who were dealing with mathematical problems regarding of chance. The best we can say is how likely they are to happen, using the idea of probability.
The word "probability" means the chance of occurrence of a particular event. Solution Let us assume A is the event of teenagers owning only a cycle and B is the event of teenagers owning only a bike. Problem Consider three pen-stands.
What is the probability that a student plays volleyball given that the student plays cricket? To find the defective laptops all of them are tested one-by-one at random.
Probability can be conceptualized as finding the chance of occurrence of an event. What is the probability that a teenager owns bike given that the teenager owns a cycle?
If the occurrence of one event is not influenced by another event, they are called mutually exclusive or disjoint. The first pen-stand contains 2 red pens and 3 blue pens; the second one has 3 red pens and 2 blue pens; and the third one has 4 red pens and 1 blue pen.
Mathematically, it is the study of random processes and their outcomes. There is equal probability of each pen-stand to be selected.
We often Discrete math prob to guess the results of games of chance, like card games, slot machines, and lotteries; i. What is the probability to find both of the defective laptops in the first two pick? Solution Let A be the event that we find a defective laptop in the first test and B be the event that we find a defective laptop in the second test.
Solution Let us assume A is the event of students playing only cricket and B is the event of students playing only volleyball. If one pen is drawn at random, what is the probability that it is a red pen?
Problem 3 Six good laptops and three defective laptops are mixed up. The laws of probability have a wide applicability in a variety of fields like genetics, weather forecasting, opinion polls, stock markets etc. Tossing a fair coin is an example of random experiment.
After tossing a coin, getting Head on the top is an event. Before proceeding to details of probability, let us get the concept of some definitions. Next Page Closely related to the concepts of counting is Probability.This ability is important for software engineers, data scientists, security and financial analysts (it is not a coincidence that math puzzles are often used for interviews).
We cover the basic notions and results (combinatorics, graphs, probability, number theory) that are universally needed. By contrast, discrete math, in particular counting and probability, allows students—even at the middle school level—to very quickly explore non-trivial "real world" problems that are challenging and interesting.
Discrete math shows up.

"It is an excellent general basic textbook in Discrete Mathematics and Probability.
This book's raison d'être is to provide a hands-on textbook with enough pictures and diagrams to appeal to visual learners and make logic, set theory and probability more accessible.4/5(1). Discrete Mathematics Warmups If there are only a handful of objects, then you can count them with a moment's thought, but the techniques of combinatorics can extend to quickly and efficiently tabulating astronomical quantities.
