I'm assuming the question is referring to a game of skee ball or something similar. In this case, there are many holes in the scoring area, and the probability of landing in the 40 point hole would be the area of the hole divided by the area of the entire scoring zone. Therefore:

1.) If the size of the 40 point hole is enlarged, the probability: INCREASES

This is because the hole now takes up more of the total area.

2.) If the 40 point hole is made smaller the probability: DECREASES

This is because the hole now takes up less of the total area.

3.) If the 40 point hole stays the same size but the scoring zone is made smaller, the probability: INCREASES

This is because there is less total area, which in turn means that the hole which was not changed now takes up a larger percentage of the scoring zone.
