Question

Question 6
Three coins were tossed 30 times simultaneously. Each time the number of heads occurring was noted down as follows:
$\begin{array}{cccccccccc}0& 1& 2& 2& 1& 2& 3& 1& 3& 0\\ 1& 3& 1& 1& 2& 2& 0& 1& 2& 1\\ 3& 0& 0& 1& 1& 2& 3& 2& 2& 0\end{array}$
Prepare a frequency distribution table for the data given above.

Answer 1

By observing the data given above, the required frequency distribution table can be constructed as follows.
$\begin{array}{cc}\text{Number of heads}& \text{Number of times(frequency)}\\ 0& 6\\ 1& 10\\ 2& 9\\ 3& 5\\ \text{Total}& 30\end{array}$
