Two dice are thrown together. The probability that at least one will show its digit $6$ is

The probability of getting a number greater than $2$ in throwing a die is

Let $E _{1}, E _{2}, E _{3}$ be three mutually exclusive events such that $P \left( E _{1}\right)=\frac{2+3 p }{6}, P \left( E _{2}\right)=\frac{2- p }{8}$ and $P \left( E _{3}\right)$ $=\frac{1- p }{2}$. If the maximum and minimum values of $p$ are $p _{1}$ and $p _{2}$, then $\left( p _{1}+ p _{2}\right)$ is equal to.

Describe the sample space for the indicated experiment: A coin is tossed three times.

There are $n$ letters and $n$ addressed envelopes. The probability that all the letters are not kept in the right envelope, is

One card is drawn from a well shuffled deck of $52$ cards. If each outcome is equally likely, calculate the probability that the card will be a diamond
