What is the most probable number of successes in 10 trials with probability of success `2/3`? (d) 4 (b) 7 (a) 10 (c) 5

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

If the probability of success of an experiment is 0.4 . What is the probability of failure ?

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 :

A die is thrown 5 times. If getting an even number is a success, what is the probability of 3 successes ?

In a series of 3 independent triais the probability of exactly 2 success is 12 xx as image as the probability of 3 successes.The probability of a success in each trial is: (A) (1)/(5) (B) (2)/(5) (C) (3)/(5) (D) (4)/(5)

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.
