Define a trial.

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.

The probability of securing a succes in an trial is three times that of a failure. The probability of getting atleast 4 successes in 5 trial is

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.

In a sequence of independent trials, the probability of the success in one trial is 1/4 . Find the probability that the second success takes place on or after the fourth trial in 6 trials.

The probability of happening an event A in one trial is 0.4. Find the probability that the event A happens at least one in three independent trials.

The probability of happening an event A in one trial is 0.4. Find the probability that the event A happens at least one in three independent trials.

The probability of happening an event A in one trial is 0.4. Find the probability that the event A happens at least one in three independent trials.

The probability of happeining an event A in one trial is 0.4. Find the probability that the event A happens at least once in three independent trials.
