Three coins were tossed $30$ times simultaneously. Each time the number of heads occurring was noted down as follows:
$\begin{array}{llllllllll}0 & 1 & 2 & 2 & 1 & 2 & 3 & 1 & 3 & 0 \\ 1 & 3 & 1 & 1 & 2 & 2 & 0 & 1 & 2 & 1 \\ 3 & 0 & 0 & 1 & 1 & 2 & 3 & 2 & 2 & 0\end{array}$

(N/A) To prepare the frequency distribution table,we count the occurrences of each outcome (number of heads) in the given data set.
$1$. Count of $0$ heads: $6$ times.
$2$. Count of $1$ head: $10$ times.
$3$. Count of $2$ heads: $9$ times.
$4$. Count of $3$ heads: $5$ times.
Sum of frequencies: $6 + 10 + 9 + 5 = 30$.
Number of heads Number of times (frequency)
$0$ $6$
$1$ $10$
$2$ $9$
$3$ $5$
Total $30$
