How many 3-digit numbers can be formed from the digits 5 6 7 8 and 9 of the digits are distinct?

We can make 120 three digit distinct numbers.

How many 3-digit numbers are there more than 600?

The units place can be filled in by the remaining 3 digits in 3 ways. Hence, by fundamental counting principle, we can form 2 × 4 × 3 = 24 numbers of three digits greater than 600 by using the digits 1, 2, 5, 6 and 8, without repeating the digits.

How many three digit numbers are there which are less than 600 and even?

Hence, there are a total of eight three-digit even numbers less than 600 that can be formed with the digits 3,3,4,8,9 if each digit is used at most once. In all, we can form 2+6+8=16 even numbers less than 600 using the digits 3,3,4,8,9 at most once.

How many number can you make using 3/5 and 7?

Question 3: What numbers can you make using 3, 5 and 7? You can make 357 and 537. What others? Answer: The other numbers that you can make using 3, 5 and 7 by keeping one of the numbers fixed at the beginning are 375, 573, 735 and 753.

How many positive integers less than 500 can be formed using?

How many positive integers less than 500 can be formed using the numbers 1, 2, 3, and 5 for digits, each digit being used only once. Solution: Single digit numbers can be formed in 4 ways. 3 digit number less than 500 can be formed in 3 * 3 * 2 = 18 ways.

Can a 4 digit number be greater than 600?

Any 4 digit number is greater than 600. Thanks. Four digit numbers: Since there are four digits, four slots, and no replacement allowed, there are 4!=24 such arrangements. Three digit numbers: The first number must start with 6, 7, or 8 (in order to be >600), so 3 choices.

How many unchosen digits are there between 330 and 400?

Case 1: All those between 330 and 400 Choose the first digit 1 way (as 3) That leaves 6 unchosen digits. Choose the second digit any of 3 ways, 4,5, or 6 That leaves 5 unchosen digits Choose the third digit any of these 5 ways.

How many unchosen numbers are there in the number system?

There are 7 unchosen digits. Choose the last digit any of 3 ways, 1,3,or 5 That leaves 6 unchosen digits, including 0. Choose the first digit any of 5 ways. (Can’t choose 0). That leaves 5 unchosen digits including 0. Choose the middle digit any of these 5 unchosen ways.

How many 3 digit numbers can be repeated but not repeated?

So the number of 3 digits numbers where no digit is repeated and is less than 800 is 5 x 5 x 4… that is 100 So in order to satisfy the number 3 cannot be repeated. First digit can be 3,4,5,6,7,8 -2 digits which were used earlier (4 digits only). So in order to satisfy the number 3 cannot be repeated.
