A dice is thrown 100 times . If getting an even number is considered a success , then the variance of the number of successes is

A die is tossed twice. Getting a number greater than 4 is considered a success. Then the variance of the probability distribution of the number of success is

A die is thrown 10 times. If getting an even number is considered as a success, then the probability of four successes is

A die is rolled 3 times. If getting a one is considered as a success, then the probability of 2 successes is

A pair of dice is thrown 4 times. If getting a doublet is considered a success, find the probability distribution of the number of successes and hence find its mean.

In eight thows of a die 1 or 3 is considered a success. Then, the standard deviation of success, is

A die is thrown 20 times. Getting a number greater than 4 is considered a success. Find the mean and variance of the number of successes.

A fair coin is tossed 5 times and getting a head is considered as a success, then probability of getting at least two successes is 3/(16) (2) (31)/(32) (3) 5/(32) (4) (13)/(16)
