In an oratory competition,$30$ students participated,out of which $12$ are boys. Find the probability that the first prize is won by a girl.

Two coins are tossed $1000$ times and the outcomes are recorded as below:

Number of heads	$2$	$1$	$0$
Frequency	$200$	$550$	$250$

Based on this information,the probability for at most one head is

At a fair, $70$ boys, $80$ girls, $20$ men, and $30$ women have come. Find the probability that a person selected at random to be a prize winner is a woman.

When a balanced die is thrown,the probability of getting $3$ is .........

The probability of getting two heads when three balanced coins are tossed is ............

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 $3\,?$
