I need to know how many permutations there are for a 5 figure number and wot they will be?

the number i have is 91367, now many permutations and combinations of this number are there and what are they?

Answers:
one combination of 5 digits and 120 permutation.

one combination 5 digits can be picked in only one way

19367 91367 all are same.

for permutation
both the above are different

1st letter 5 choices , 2nd letter 4 choces so on .

number 5*4*3*2*1 = 120 choices
In the first digit there are 5 possibilities: 9 or 1 or 3 or 6 or 7. If 9 is used in the first digit, then it can't be used in the second or third or fourth or fifth. so the second place only has 4 possibilities, the third has 3, the fourth as 2 and the last has 1.

So.
5 x 4 x 3 x 2 x 1 = 120 combinations.
120
5x4x3x2x1=120
permutation means arranging certain items where the order is important and combination implies arranging different items where the order doesnt matter.. so, the combination of ur 5 digit number is one.. since 31769 is the SAME COMBINATION of 91367..
on the other hand, permutation of ur 5 digit number will be 5! which is equal to 5*4*3*2*1=120
