There are $16$ girls in a class of $40$ students. If a student is randomly selected and made a class representative, find the probability that a boy is selected.

Can the experimental probability of an event be greater than $1$? Justify your answer.

Of the $50$ students in a class, $22$ are girls. The probability that a student who gets first rank is a boy is .............

$A$ 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.

Three coins were tossed $30$ times simultaneously. Each time the number of heads occurring was noted down as follows:
$0, 1, 2, 2, 1, 2, 3, 1, 3, 0,$
$1, 3, 1, 1, 2, 2, 0, 1, 2, 1,$
$3, 0, 0, 1, 1, 2, 3, 2, 2, 0$
Prepare a frequency distribution table for the data given above.

The marks obtained by a student in five tests are as follows:

Test Number	Marks obtained
$1$	$62$
$2$	$72$
$3$	$78$
$4$	$91$
$5$	$85$

If one of the tests is chosen at random,find the probability that the student scored $(1)$ more than $90$ marks and $(2)$ between $70$ and $80$ marks in that test.
