Answer:

The answer is the first one "If they play a large number of turns, they should expect to average about 1.5 points per turn."

Explanation:

This is essentially, because the 1st answer makes sense, while the other two are kind of ridiculous. Saying that the amount of points are exactly 3 points is not true, and saying it is possible to get 1.5 points on a turn is also impossible.
