The probability of a person hitting a bird is $3/4$. If he tries $5$ times,what is the probability that he will not hit the bird even once (in $/1024$)?

Let $\lim _{t \rightarrow 0}(1+5 t)^{\frac{1}{t}}=K$ and $X$ be the random variable representing the number of successes in $100$ independent trials. If the probability of success in each trial is $0.05$, then the probability of getting at least one success is

In tossing $10$ coins,the probability of getting exactly $5$ heads is

If the sum of mean and variance of a binomial distribution for $5$ trials is $1.8$,then the probability of success is:

The mean and variance of a binomial distribution are $4$ and $2$ respectively. Then the probability of exactly two successes is

$A$ dice is thrown $10$ times. If getting an even number is considered as a success,then the probability of $4$ successes is:
