The probability of a month of February having $5$ Mondays in a leap year is ............

$A$ card is drawn at random from a well-shuffled pack of $52$ cards. Find the probability of that card being a queen.

In a medical examination of students of a class,the following blood groups are recorded:

Blood group	$A, AB, B, O$
Number of students	$10, 13, 12, 5$

$A$ student is selected at random from the class. The probability that he/she has blood group $B$,is:

$A$ die is thrown $1000$ times and the outcomes were recorded as follows:

Outcome	$1$	$2$	$3$	$4$	$5$	$6$
Frequency	$180$	$150$	$160$	$170$	$150$	$190$

If the die is thrown once more,then the probability that it shows $5$ is:

$50$ families with $2$ children were selected randomly and the following data were recorded:

Number of girls in a family	$0$	$1$	$2$
Number of families	$10$	$32$	$8$

If a family is chosen at random,compute the probability that it has: $(1)$ two girls,$(2)$ one girl,$(3)$ no girl.

Two dice are thrown simultaneously $500$ times. Each time the sum of two numbers appearing on their tops is noted and recorded as given in the following table:

Sum	Frequency
$2$	$14$
$3$	$30$
$4$	$42$
$5$	$55$
$6$	$72$
$7$	$75$
$8$	$70$
$9$	$53$
$10$	$46$
$11$	$28$
$12$	$15$

If the dice are thrown once more,what is the probability of getting a sum more than $10\,?$
