How many different permutations are there of 4 objects taken 4 at a time?
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.
How many permutations of 8 objects are there taken 2 at a time?
The number of permutations of 8 objects taken 2 at a time is calculated using the formula for permutations, which is ( P(n, r) = \frac{n!}{(n-r)!} ). For this case, ( n = 8 ) and ( r = 2 ), so it can be expressed as ( P(8, 2) = \frac{8!}{(8-2)!} = \frac{8!}{6!} = 8 \times 7 = 56 ). Therefore, there are 56 permutations of 8 objects taken 2 at a time.

How many permutations and combinations are there of 4 objects taken 3 at a time?
Permutations = 4 x 3 x 2 = 24Combinations = (4 x 3 x 2) / (3 x 2 x 1) = 24/6 = 6

How many 3 number combinations are possible with 1234?
Just 4: 123, 124, 134 and 234. The order of the numbers does not matter with combinations. If it does, then they are permutations, not combinations.
