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

$A$ box contains $100$ cards marked with numbers $1$ to $100$. If one card is drawn at random from the box,find the probability that the number on the card is: $(1)$ a multiple of $7$,$(2)$ a number smaller than $30$,$(3)$ a prime number.

The distribution of the weights of $50$ students in a class is as follows:

Weight (in $kg$)	Number of students
$50-52$	$10$
$52-54$	$12$
$54-56$	$13$
$56-58$	$9$
$58-60$	$6$

Find the probability that a student selected at random weighs $56 \ kg$ or more.

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

Three coins are tossed simultaneously $500$ times with the following frequencies of different outcomes:

Number of heads	$0$	$1$	$2$	$3$
Frequency	$70$	$190$	$175$	$65$

Find the probability of getting $0, 1, 2$ or $3$ heads.
Verify that the sum of all these probabilities is $1$.

State whether each of the following statements is true or false:
$(1)$ The probability that the month of February in a leap year has $5$ Saturdays is $0$.
$(2)$ The probability of getting $51$ marks in a $100$ marks examination is $\frac{1}{101}$.
