15. Consider a fair tetrahedral die with faces numbered 1, 3, 5, 7. Two of
these dice are tossed. Find each probability.
a. P(sum is even) b. P(sum is odd) c. P(sum is 8)

explanation:

step-by-step explanation:

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.

step-by-step explanation:

hihi so drawing these 2 triangles is fairly simple. all that's left is finding the height of each one. luckily, we have a side length and an angle, so there is a trig function we can use to solve for the height. the easiest one to use would be tangent, since we have 2/3 things needed to find and the third needed is what we are solving for. tan(73°) * 30 ~= 98.13 and tan(73°) * 35 ~= 114.45
