Answer:
100 numbers
Step-by-step explanation:
We only want three-digit numbers, so let's provide three spaces:
__ __ __
The first number can be 2, 6, 7, or 9; it can't be 1 because then we're going to have a number in the 100s, which will be less than 200 (and that's not allowed). So, there are 4 ways to choose the first number.
The second number, though, can be any of the 5 numbers because once we've established the first number, the second digit is anything. So there are 5 ways to choose this one.
Finally, there are also 5 digits to choose from for the last digit because we can reuse digits.
Multiply these together:
4 * 5 * 5 = 100
There are 100 three-digit numbers greater than 200 that can be formed with the given digits.
Answer:
100
Step-by-step explanation:
100
Step-by-step explanation:
If three-digit numbers greater than 200 can be formed from the digits 1, 2, 6, 7, and 9
Here we have total number of digits are 5
We need to make 3-digit number which is greater than 200
First digit must be 2 or greater than 2
From list of number 1,2,6,7,9
Four numbers are greater than equal to 2
For 1st place total number of possibility = 4
For 2nd place number of possibility = 5
For 3rd place number of possibility = 5
Total numbers of which are greater than 200 = 4 x 5 x 5 = 100
Hence, 100 three-digit number greater than 200
