The first object in the row can be any one of the 4 objects. For each of those . . .
The second one in the row can be any one of the remaining 3 objects. For each of those . . .
The third one in the row can be either of the remaining 2 objects.
The total number of different arrangements is (4 x 3 x 2) = 24 ways.
seven
4! = 4 * 3 * 2 * 1 = 24 ways[1]
24 Ways, 4 x 3 x 2 x 1 = 24
thats simple, just do 4!, which is 4 times 3 times 2 times 1, which gives you 24.
Seven symbols can be arranged in (7 x 6 x 5 x 4 x 3 x 2) = 5,040 ways.
You can arrange 4 in 2 ways 1x4 and 2x2.
