His mean score for the first 4 games will be 18 points.

Step-by-step explanation

In the first 3 games, the mean of the scores is 15 points . Mean is the simple average of some numbers.

So, the total score in first 3 games =
(15*3)= 45 points

Now, in the 4th game, he scored 27 points. So, the total score in the first 4 games =
45+27= 72 points

Thus, the average of scores in first 4 games =
(72)/(4) = 18 points

So, his mean score for the first 4 games will be 18 points.
