The probability that a marksman will hit a target is given as $1/5$. Then his probability of at least one hit in $10$ shots is:

If $15$ coins are tossed,then the probability of getting $10$ heads is:

What is the probability of getting at least $1$ tail when a coin is tossed $4$ times?

$A$ die is tossed $5$ times. Getting an odd number is considered a success. Then the variance of the distribution of success is

Let in a Binomial distribution,consisting of $5$ independent trials,probabilities of exactly $1$ and $2$ successes be $0.4096$ and $0.2048$ respectively. Then the probability of getting exactly $3$ successes is equal to ....... .

If the mean and the variance of a Binomial variate $X$ are $2$ and $1$ respectively,then the probability that $X$ takes a value greater than $1$ is equal to
