Pentagons are five sided figures, in which each of the five sides are equal. To figure out the perimeter, you take the side given and multiply it by 5 since each side is the same. I'll do the first one for you and you can do the rest. 6 * 5 = 30.

When you have a < sign you either shade under or to the left of the line, depending on what kind of line it is. It has a dotted line. A > sign you shade either to the right or above the line. This also has a dotted line. If you have a <= or >=, the line is solid.

Right now the probability of picking blue would be 12/30. If you add another blue it would be 13/31, then 14/32, 15/33, 16/34, 17/35, 18/36. 18/36=1/2, so if he wants the probability to be 1/2 he needs to add 6 more blue.
