Which one is not a requirement of a binomial distribution? a. There are 2 outcomes for each trial b. There is a fixed number of trials c. The outcomes must be dependent on each other d. The probability of successes must be the same for all the trials.

Which one is not a requirement of a binomial distribution? There are 2 outcomes for each trial There is a fixed number of trials The outcomes must be dependent on each other The probability of successes must be the same for all the trials.

IF the mean and S.D. of binomial distribution are 20 and 4 respectively. Than the number of trials , is

In a series of three trials , the probability of two successes is 9 times the probability of three successes . Then the probability of success in each trial is :

Examine, If two coins are tossed at the same time, there are 3 possible outcomes two heads, two tails, or one of each. Therefore, for each outcome, the probability of occurrence is 1//3 .

Three houses are available in a locality . Three persons apply for the houses . Each applies for one house without consulting others . The probability that all three apply for same house is

A and B play a game where each is asked to select a number from 1 to 25 . If the two numbers match ,both of them win a prize . The probability that they will not win a prize in a single trial is ,

An artillery target may be either at point I with probability 8/9 or at point II with probability 1/9 we have 55 shells, each of which can be fired either rat point I or II. Each shell may hit the target, independent of the other shells, with probability 1/2. Maximum number of shells must be fired a point I to have maximum probability is 20 b. 25 c. 29 d. 35

An artillery target may be either at point A with probability (8)/(9) or at point B with probability (1)/(9) , we have 21 shells, each of which can be fired either at point A or at point B. Each shell may hit the target independently of the other shells, with probability (1)/(2) How may shells must be fired at point A to hit the target with maximum probability ?

For 6 trials of an experiment, let X be a binomial variate which satisfies the relation 9P(X = 4) = P(X = 2) . Find the probability of success.

A can hit a target 4 times out of 5 trial. B can hit 3 times of 4 trials and C can hit 2 times out of 3 trials. If all three hit the target sumultaneously, find the probability of hitting the target.
