The Pythagorean Theorem is a^2 +b^2 = c^2, where a and b are the sides and c is the hypotenuse ( angled line).


3.

a^2 + 6^2 = 18^2

a^2 + 36 = 324

a^2 = 324 - 36

a^2 = 288

a =√288

a = 12√2


4.

a^2 + 3^2 = 9^2

a^2 + 9 = 81

a^2 = 81-9

a^2 = 72

a = √72

a = 6√2

Bumek [7]

Answer:

If you hope to get the rare Deathcharger's Reins mount from Baron Rivendare for example, we know that it has a 1% drop chance. That means that every time you kill the Black Baron you have a 1% chance of getting the mount. 1% on the first kill, and 1% on the 100th kill. However, over the course of 100 kills, you have a much higher probability of getting the mount. But not 100%. Never 100%.
