Is the number of permutations of two items from a data set is always two times the number of combinations when taking two objects at a time from the same data set?
Yes
How many 4 number combinations are there using 1 2 3 4 5?
There are 120 permutations and 5 combinations.
How many5 number combinations are there in the numbers1to43?
On a calculator: 43C5 = 962598 This is for combinations and not permutations, so in essence, the order of the 5 number combinations does not matter. Yours Truly, Mr Greatness
How many different combinations are possible is a coin is tossed once and a number cube is tossed twice?
The number of combinations - not to be confused with the number of permutations - is 2*21 = 42.
How many combinations does 3 tick-boxes have?
There are only four combinations but there are 8 permutations.

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.
The number of permutations of 5 things taken 2 at a time is 20?
Not quite. Number of combinations is 20, number of permutations is 10. Any 2 from 5 is 10 but in any order doubles this.
How many combinations are there if there are 8 numbers and you have a 16 number combination?
Assuming that "number" means digits and that it is permutations (rather than combinations) that are required, the answer is 816 which is 281.475 trillion (approx).
How many combinations are there in a seven digit phone number?
There is only one combination. There are many permutations, though.
How many combinations does 3 tick-boxes have?
There are only four combinations but there are 8 permutations.
How many times a three digit number is divisible by 5 in permutations and combinations?
It depends on how many digit you are choosing from.
How many 3 digit combinations can be made from 1 to 9?
All the numbers from 0 to 999 so 1000 numbers However if you mean only using each number once the answer is about 720 * * * * * No. The above answer refers to the number of permutations. Permutations are NOT the same as combinations as anyone who has studies any probability theory can tell you. The number of combinations is 9C3 = 9*8*7/3*2*1 = 84
How many different combinations of 5 numbers 5 number combination?
120 WRONG! That is the number of PERMUTATIONS. In the case of combinations, the order of the numbers does not matter, so there is only 1 5-number combination from 5 numbers.
