A child has a die whose six faces show the letters as given below:

$\boxed{\mathrm{A}}, \boxed{\mathrm{B}}, \boxed{\mathrm{C}}, \boxed{\mathrm{D}}, \boxed{\mathrm{E}}, \boxed{\mathrm{A}}$

The die is thrown at random once. What is the probability of getting an $\mathrm{A}$ in fraction.

A child has a die whose six faces show the letters as given below:
$\boxed{A}, \boxed{B}, \boxed{C}, \boxed{D}, \boxed{E}, \boxed{A}$
The die is thrown at random once. What is the probability of getting the letter $B$?

Find the probability that a non-leap year chosen at random has exactly $52$ Sundays.

Find the probability that a non-leap year chosen at random has $53$ Sundays.

An urn contains $8$ red, $6$ white, and $4$ black balls. A ball is drawn at random from the urn. If the probability of drawing a red or white ball is $\frac{k}{9}$, then find the value of $k$.

An urn contains $8$ red, $6$ white, and $4$ black balls. A ball is drawn at random from the urn. Find the probability that the drawn ball is neither black nor white.

A bag contains $19$ cards, bearing numbers $1, 2, 3, ... , 19$. A card is drawn at random from the bag. Find the probability that the number on the drawn card is prime. Write the final answer in the simplest fraction form.

A bag contains 19 cards, bearing numbers  $1, 2, 3, ... , 19$. A card is drawn at random from the bag. Find the probability that number on the drawn card is divisible by $3$.
