In this question, we're given the word algorithms.
00:05
So take note that there is a total of 10 distinct letters.
00:12
Distinct means you can tell them apart.
00:14
There are no repeats here.
00:17
We want to find the number of ways to rearrange all the letters.
00:21
Now in general, if i have n distinct objects and i want to arrange these n distinct objects in a row or in a line, it will be n factorial ways.
00:38
So in this case, i have 10 distinct letters in the word algorithm.
00:42
So number of ways to rearrange all the letters will be 10 factorial ways.
00:47
And that would be this number of ways.

In the next question, we're given a club.
01:00
It has 10 students.
01:02
And the club wants to elect a president, a vice president, treasurer and secretary...
