Step-by-step explanation: p(roll a 2) means the probability or likelihood of rolling a 2. So to find the probability of rolling a 2, let's use our ratio for the probability of an event which is shown below.
Number of favorable outcomes/total number of outcomes
Since only one side of a number cube has a 2 on it, the number of favorable outcomes for rolling a 2 is 1 and since there are six sides to a number cube and it's equally likely that the cube will land on any of these sides, the total number of outcomes is 6. So the probability of rolling a 2 is 1/6.
I have also shown my answer in the image attached.
Answer: The sum of the measures of the interior angles of a polygon is always 180(n-2) degrees, where n represents the number of sides of the polygon. The sum of the measures of the exterior angles of a polygon is always 360
