Probability Questions

Dear Aspirants, the probability is one of the important topics in the quantitative aptitude section. Probability aptitude questions will be asked in the application sums problems otherwise it will be asked as application DI. Probability questions and answers pdf with detailed explanations for banking, Railway, SSC, and other competitive examinations are provided here. Important shortcuts and tricks for probability questions and answers pdf in the quantitative aptitude section are also provided here. Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty. Guidely provides you with the new pattern questions that are asked in the examination with solutions in detail. Candidates can make use of these probability aptitude questions and answers with detailed explanations for their effective preparation. We provide aptitude quizzes on a daily basis to improve your performance in the exam.

Sample space in concept of probability means all the possible outcomes of an experiment as a whole, from the Sample Space. Probability is the branch of mathematics concerning the occurrence of a random event, and four main types of probability exist: classical, empirical, subjective, and axiomatic. Probability is synonymous with possibility, so you could say it’s the possibility that a particular event will happen. Probability is a chase or possibility of an event occurring. To ace, the application problems like probability examples in the SBI PO, SBI Clerk, IBPS Clerk, IBPS PO, and other competitive exams, practice all kinds of problems and analyze the solutions provided. Daily practice of quantitative aptitude questions is a must. Here you can find various types of problems. Quantitative aptitude questions and answers with explanations are available. Learn new shortcuts and mind math tricks from the shortcuts provided and solve these questions. Many candidates feel the quantitative aptitude section is the tougher one because of the calculation time and ability to remember the formulas.

The formula for concept of probability states that the possibility of an event happening, or P(E), equals the ratio of the number of favorable outcomes to the number of total outcomes. Mathematically, it looks like this: P(E) = favorable outcomes/total outcomes. A sample space is the set of possible outcomes that can occur in a trial. For example, when tossing a coin, the set of possible outcomes is {heads, tails}. Or when rolling a single die, the set of possible outcomes is {1, 2, 3, 4, 5, 6}. An outcome is a possible result you can get from doing a trial or experiment. For example, you could get heads when tossing a coin. The classical or theoretical perspective on probability examples states that in an experiment where there are X equally likely outcomes, and event Y has exactly Z of these outcomes, then the probability of Y is Z/X or P(Y) = Z/X. This is often the first perspective that students experience in formal education. The subjective perspective on probability considers a person’s own personal belief or judgment that an event will happen. The empirical or experimental perspective on concept of probability defines probability examples through thought experiments. The axiomatic perspective on concept of probability is a unifying perspective where the coherent conditions used in theoretical and experimental concept of probability prove subjective probability examples.
