A number that exceeds one million is to be formed from the digits 3, 2, 0, 4, 3, 2, 3.
Then the numbers should be any number of 7 digits which can be formed from these digits. Also, among the given numbers 2 is repeated twice and 3 is repeated thrice.
∴ Required number of numbers = Total
number of arrangements possible among these digits – number of arrangements of 7 digits which begin with 0.
