10*9*8 = 720
6*5*4*3*2*1=720
How many different ways can we arrange 9 objects taken 3 at a time?
6*5*4*3*2*1 = 720
Permutations of 10 letters taken 3 a time = 10 x 9 x 8 = 720
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.
There are 24 different arrangements of 4 numbers (4 factorial or 4!). If you allow numbers to be repeated then the figure becomes 256 (44)
There is just 1 combination of 8 numbers taken 8 at a time.
There are 3780 different arrangements.
6*5*4*3*2*1=720
How many different ways can we arrange 9 objects taken 3 at a time?
6*5*4*3*2*1 = 720
8*7/(2*1) = 28
One is not sure when the powerball numbers are said. It is normally said after everyone has taken the numbers. Many times there will be some suspense.
The number of different permutations of 4 objects taken 4 at a time is calculated using the formula ( n! ), where ( n ) is the number of objects. For 4 objects, this is ( 4! = 4 \times 3 \times 2 \times 1 = 24 ). Therefore, there are 24 different permutations.
Permutations of 10 letters taken 3 a time = 10 x 9 x 8 = 720
There are 172 different arrangements.
There are 7!/(2!*2!) = 1260 arrangements.
