How many different ways can we arrange 9 objects taken 3 at a time?
In 6 way
24 Ways, 4 x 3 x 2 x 1 = 24
4! = 4 * 3 * 2 * 1 = 24 ways[1]
Seven symbols can be arranged in (7 x 6 x 5 x 4 x 3 x 2) = 5,040 ways.
4! = 4*3*2*1 = 24 ways
24, 1*2*3*4
In a line in 6! = 6*5*4*3*2*1 = 720 ways.
The answer is 50P3 = 50*49*48/(3*2*1) = 117,600
How many different ways can we arrange 9 objects taken 3 at a time?
4! 4 * 3 * 2 = 24 ways ==========
The answer is 5 factorial or 5*4*3*2*1 or 120
3! = 1 x 2 x 3 = 6 ways.
If you have three DIFFERENT letters, you can arrange them in 3! = 1 x 2 x 3 = 6 different ways.
3*2*1 = 6 ways.
3!=>3*2*1=6ways
Choose 3 then 2 then 1; 3*2*1 = 6 ways.
