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

Two coins are tossed simultaneously $400$ times with the following frequencies of different outcomes:
Two heads: $100$ times
One head: $220$ times
No head: $80$ times
Find the probability of occurrence of each of these events.

$A$ recent survey found that the ages of workers in a factory is distributed as follows:

Age (in years)	$20-29$	$30-39$	$40-49$	$50-59$	$60$ and above
Number of workers	$38$	$27$	$86$	$46$	$3$

If a person is selected at random,find the probability that the person is having age from $30$ to $39$ years.

Here is an extract from a mortality table.

Age (in years)	Number of persons surviving out of a sample of one million
$60$	$16090$
$61$	$11490$
$62$	$8012$
$63$	$5448$
$64$	$3607$
$65$	$2320$

Based on this information,what is the probability of a person aged $60$ dying within a year?

Over the past $200$ working days,the number of defective parts produced by a machine is given in the following table:

Number of defective parts	$0$	$1$	$2$	$3$	$4$	$5$	$6$	$7$	$8$	$9$	$10$	$11$	$12$	$13$
Days	$50$	$32$	$22$	$18$	$12$	$12$	$10$	$10$	$10$	$8$	$6$	$6$	$2$	$2$

Determine the probability that tomorrow's output will have more than $13$ defective parts.

When a balanced die is thrown,find the probability of receiving a composite number.
