The probability of failure is `0.25%.` What is the probability of success ?

If probability of success is 63% , what is the probability of failure?

The outcome of a random experiment results in either success or failure. If the probability of success is twice the probability of failure, then the probability of success is ............

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.

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 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 :

If in a trial the probability of success is twice the probability of failure. In six trials the probability of at least four successes is

If in a trial the probability of success is twice the probability of failure. In six trials the probability of at least four successes is

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
