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

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

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

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.

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 ............

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

Consider 5 independent Bernoulli's trials , each with probability of success p . If the probability of at least one failure is greater p , If the probability of at least one failure is greater than or equal to 31/32 , then p lies in the interval :
