If getting 5 or 6 in a throw of an unbiased die is a success and the random variable `X` denotes the number of successes in six throws of the die, find `P(X >=4)` .

If getting 5 or 6in a throw of an unbiased die is a success and the random vriable X denotes the number of successes in six throws of the die,find P(X=4)

If getting '5' or '6' in a throw of an unbiased dice is a success and the random variable 'X' denotes the number of success in six throws of the dice, find P(Xge4).

If getting a '5' or a '6' in the throw of an unbiased die is a 'success' and the random variable 'X' denotes the number of successes in six throws of the die, find P_X[Xge4]

If getting a '5' or a '6' in the throw of an unbiased die is a 'success' and the random variable 'X' denotes the number of succeses in six throws of the die, find P_(X)[X = 4, 5 , 6] .

A die is thrown thrice.A success is or 6 in a throw.Find the mean and variance of the number of successes.

A die is thrown thrice. A success is 1 or 6 in a throw. Find the mean and variance of the number of successes.

Find the mean and variance of the number obtained on a throw of an unbiased die.

Find the mean and variance of the number obtained on a throw of an unbiased die.

A die is rolled twice. Getting a number greater than 4 is called a 'Success'. Let the random variable X is equal to the number of successes then mean of X is
