How many 4 digit numbers can be formed from the digits 7341 if none of the digits can be repeated?
24
How many four-digit numbers each less than 700 can be made using digits 1 3 4 5 7 8 9 if repetition is allowed?
None.
How many ways are there to write a 3-digit positive integer using digits 1 3 5 7 and 9 if no digit is used more than once?
There are 5 choices for the first digit, as any of the 5 given digits can be used. After selecting the first digit, there are 4 remaining choices for the second digit, and 3 choices for the third digit. Therefore, the total number of ways to write a 3-digit positive integer using the given digits without repetition is 5 x 4 x 3 = 60 ways.
How many three digit numbers have digits that add up to zero?
None. The only way for it to be possible would be 3 zeros which is not considered a 3 digit numbers.
Do you already know the correct answer to a hypothesis before you being collecting data?
