If $\displaystyle 5\%$ of the electric bulbs manufactured by a company are defective, use Poisson distribution to find the probability that in a sample of $\displaystyle 100$ bulbs, $\displaystyle 5$ bulbs will be defective. [Given : $\displaystyle e^{-5} = 0.007$ ]

If the first quartile ($\displaystyle Q_1$) and third quartile ($\displaystyle Q_3$) of a normal distribution are 22 and 28, what is the median of the distribution?

The Mode of binomial distribution $\displaystyle B(7, \frac{1}{3})$ is

If $\displaystyle p$ is increased for a fixed $\displaystyle n$; the Binomial distribution shifts to the

The variance of a binomial distribution with parameters $\displaystyle n$ and $\displaystyle p$ is:

An example of a bi-parametric discrete probability distribution is
