$A$ number is chosen at random from the single-digit natural numbers. The probability that the number chosen is a multiple of $3$ 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 less than or equal to $5$?

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 $1$.

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