Three coins were tossed $30$ times simultaneously. Each time the number of heads occurring was noted down as follows:
$0, 1, 2, 2, 1, 2, 3, 1, 3, 0,$
$1, 3, 1, 1, 2, 2, 0, 1, 2, 1,$
$3, 0, 0, 1, 1, 2, 3, 2, 2, 0$

(A) To prepare the frequency distribution table,we count the occurrences of each possible number of heads $(0, 1, 2, 3)$:
- Number of heads $0$: Occurs $6$ times.
- Number of heads $1$: Occurs $10$ times.
- Number of heads $2$: Occurs $9$ times.
- Number of heads $3$: Occurs $5$ times.
Total count = $6 + 10 + 9 + 5 = 30$.
Number of headsFrequency (Number of tosses)
$0$$6$
$1$$10$
$2$$9$
$3$$5$
