A man performs 10 trials of an experiment, if the probability of getting '4 sucesses' is maximum, then find the probability of failure in each trial.

If in 6 trials of an experiment the probability of a successes is 5 times the probability of a failure, then find the probability of two successes.

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 :

The probability of success in a single trial of a random experiment is constant and the trial is repeated inependently seven timed, if the probability of 4 successes is equal to 3 successes, find the probability of 3 successes in 5 independent trials of the experiment.

If in a trial the probability of a success is twice the probability of failure , the probability of atleast four sucesses in six trials is

If in a certain experiment the probability of success in each trial is 3/4 times the probability of failure, then the probability of at least one success in 5 trials is

If in a certain experiment the probability of success in each trial is 3/4 times the probability of failure, then the probability of at least one success in 5 trials is

In experiment probability that event A occurs in first trail is 0.4 then ………. is the probability that in three independent trial event A occurs.
