The probability that a man aged $\displaystyle 45$ years will die within a year is $\displaystyle 0.012$. What is the probability that of $\displaystyle 10$ men, at least $\displaystyle 9$ will reach their $\displaystyle 46$th birthday? [Given $\displaystyle e^{-0.12} = 0.88692$ ]

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
