$A$ positive integer is selected at random and is divided by $9$. What is the probability that the remainder is equal to $1$ (in $/9$)?

Two cards are drawn from a pack of $52$ cards. What is the probability that one of them is a queen and the other is an ace?

In a single throw of $2$ dice,find the probability of getting a total of $11$.

$A$ die is thrown three times and the sum of the numbers obtained is $15$. What is the probability that the number $4$ appears in the first throw?

$A$ card is drawn from a well-shuffled deck of $52$ cards. Find the probability of drawing a face card.

For a biased die,the probabilities for different faces to turn up are

$Face$	$1$	$2$	$3$	$4$	$5$	$6$
$Probability$	$0.2$	$0.22$	$0.11$	$0.25$	$0.05$	$0.17$

The die is tossed and you are told that either face $4$ or face $5$ has turned up. The probability that it is face $4$ is
