Question

The table shows the points of each player scored in four games.

Players	Game I	Game II	Game III	Game IV
X	14	16	10	10
Y	0	8	6	4
Z	8	11	Did not play	13

To find mean number of points per game for $Z$, would you divide the total points by $3$ or by $4$? Why?

Answer 1

$Z^{\prime }$s Points

In $4$ games he played only $3$ games,

$\therefore$ It is divided by $3$

Mean points of $c=\frac{Totalpoints}{numberofgamesplayed}$
