How many 4-digit numbers are possible if the hundreds digit is 8 and if repetition of digits is allowed?
-4
How many strings of 3 decimal digits do not contain the same 3 digits?
How many strings of three digits are there? 000 to 999, or a total of 1000. How many strings of three digits contain the same three digits? That's 000, 111, 222 ... 999! ten in total. The difference is your answer: 1000-10 = 990.
How many 3 digit numbers can be formed from the digits 24578 if no digits can be repeated?
There are 5*4*3 = 60 such numbers.
How many 3 digit numbers can be formed?
It depends upon whether the numbers can be used more than once. If the numbers can be used more than once, then there are 1,000 possible combinations; if not, then there are 720 possible combinations. ========== Assuming you are talking about integers you can calculate it this way: you can have any one of 9 digits for the first digit (zero is excluded because that would make it only a 2 digit number) You can have any one of 10 digits for the second and any one of 10 digits for the third digit. That gives you 9x10x10 = 900 different combinations for 3 digit numbers (not 1000). If you can include both negative and positive numbers as different numbers you get twice as many (2x900=18000). If you can count decimal numbers as 3 digit numbers (i.e. not restricted to integers) you can have 900 integers, 900 with the form xx.x, 1000 with the form x.xx (if zero is permitted to be the first digit and count as one of the 3 digits) or 900 (if a leading zero is NOT counted as one of the 3 digits). If a leading zero is NOT counted as one of the 3 digits, you could also have 1000 numbers of the form 0.xxx or just .xxx
How many 4 digit numbers can be formed from the digits 7341 if none of the digits can be repeated?

How many digits in the numbers between 1000 and 1128?
123
How many digits are there between 1 and 1000?
Not couting 1 and 1000, there would be 998 numbers.
How many numbers are there between 100 and 1000 such that atleast one of their digits is 7?
252 of them.
How many numbers between 100 and 1000 have their digits adding up to 5?
16
How many numbers between 100 and 1000 have 2 as the units digits?
91.
How many numbers are there between 0 and 1000 which have exactly one of their digits as 5?
it s 243..
How many digits are there in all numbers inclusive from 1 to 1000?
Infinitely many. The number pi , for example, is between 1 and 1000 and, since pi is a transcendental number, it contains infinitely many digits. Plus, there are all the irrational numbers - each with infinitely many digits, and all the rationals with recurring decimals - again with infinitely many digits.
How many different whole numbers between 0 and 1000 have digits whose sum is 9?
999 are whole.
How many prime numbers are there whose square has 5 or 6 digits?
solution: we know that there are 25 prime numbers are between 1-100 and 168 prime numbers less than 1000. 100 x 100=10000(5 digits) 999 x 999=998001(6 digits) 1000 x 1000=1000000(7 digits) so our answer should be same as the number of prime numbers between 100 to 999. hence, 168-25=143. 143 prime numbers will be there less than 1000 whose square has 5 or 6 digits.
How many 3 digits positive numbers and which are they?
Numbers above 99 and under 1000 are 3-digits, all 900 of them.
How many numbers in all are there with four digits?
Highest is 9999, lowest is 1000. These and everything between them have four digits. Try subtracting 999 from 9999. If you can´t, there´s always wikianswers.
How many digits between 1 and 1128?
There are 6484 digits BETWEEN the two given numbers.
