WebbIn probability theory and statistics, a probability distribution is the mathematical function that gives the probabilities of occurrence of different possible outcomes for an experiment. It is a mathematical description of a random phenomenon in terms of its sample space and the probabilities of events (subsets of the sample space)..

WebbIf three coins are tossed, the probability of two heads is: (a) 1/8 (b) 3/8 (c) 2/3 (d) 0 MCQ 8.34 Random variable x has binomial distribution with n = 8 and p = ½.. The most … WebbWe should use the “binomial distribution” because the “probability” of obtaining “successes” in each trial is 0.30. All the “trials” are “independent” of each other. Only “two outcomes” are possible i.e. “success” or “failure”. Let “X” be the “number of successes” in “n” “number of trials” with ... Webbwhere p is the probability of success. In the above equation, nCx is used, which is nothing but a combination formula. The formula to calculate combinations is given as nCx = n! / x!(n-x)! where n represents the … signed opinion
