In IBPS PO, IBPS Clerk, SBI PO, SBI Clerk, SSC CGL, SSC CHSL and other competitive exams, Problems based on Probability Formulas are always asked.
These are the simplest set of problems that can be solved by using Probability Formulas.
By the means of Probability formulas, we measure all the possible different types of events that can occur.

Two Expected Coverage E(X) = 0 × 0.45 1 × 0.3 2 × 0.15 3 × 0.1 = 0.9 Correct calculation of expected number of cancellations in a oneweek interval. P(X95) = 0.05 Solves problem (a) (b) (i) (b) (ii) Achievement We are assuming that the attendance is normally distributed.
This is unlikely to be the case, as we might expect certain games to be fully sold out (100% attendance) e.g.If you're behind a web filter, please make sure that the domains *.and *.are unblocked.Probability is a fundamental concept in math and statistics.The word probability is the synonym of the word ‘chance’ which is frequently used in day to day life.The word probability is used in a broad sense to indicate the possibility of something to happen.In one state, 52% of the voters are Republicans, and 48% are Democrats.In a second state, 47% of the voters are Republicans, and 53% are Democrats.It tells us what the weight of the evidence is in favor of a given hypothesis. It can be defined mathematically as The Schwarz criterion is one of the easiest ways to calculate rough approximation of the Bayes Factor. One of the most common interpretations is this one—first proposed by Harold Jeffereys (1961) and slightly modified by Lee and Wagenmakers in 2013: Kass & Raftery, Bayes Factors. 773-795 Retrieved from on March 31, 2018 Lavine & Schervish. Journal of the American Statistical Association Vol. Bayes Factors: What They Are and What They Are Not. Assuming normality, P(one game has under 90% occupancy) = 0.079 Assuming attendance of each game is independent, probability is 0.0794 (c) = 3.9 x 10-5 (2 sf).Game attendance is unlikely to be independent with equal probability as games will be held at different venues with different players.
