Two standard number cubes are rolled. find each probability.
15. p(a sum equal to 2)

There are 6 possibilities for each cube (a number between 1 and 6). This means there are 36 total combinations that can occur. The only combination resulting in a sum of two is a one on each die. This will happen 1 time out of 36, so the probability is 1/36.

The graph is missing, but a similar problem is attached, the method of solution is perfectly the same.

So, Marco just want to create a new circle using segment GX as radius, that means

Remember, the area of a circle is

Using the radio, we have

Therefore, the last choice is the right answer.

(Notice that it's the same problem, just with different values, that's it)
