<span>When the order doesn't matter, we would be using the Combination.
While, when the order does matter it is called permutation.</span>
In this case, permutation would be use since there is a
ranking for the albums.
We need to choose and arrange 5 albums out of 20. Hence, the
number of possible ways will be:
<span>5/20 P = 20! Divided by (20 – 5)! = 20 x 19 x 18 x 17 x 16 =
1860480</span>
18^2 + 68^2 =
= 324 + 4,624
= 4,948
74^2 = 5,476
4,848 is not equal to 5,476.
Since the sum of the squares of the lengths of the two shorter sides is not equal to the square of the length of the longest side, the triangle is not a right triangle.
