To form even numbers greater than 50,000 using the digits 3, 4, 5, 6, 7, and 0 without repetition, we need to consider the position of the digits carefully. Since the number has to be even, the last digit must be 0. The tens digit must be even to ensure the entire number is even, so it can be either 4 or 6. The thousands digit must be 5 to make the number greater than 50,000. Therefore, the only number that fits these criteria is 56,340.
There are 5*4*3 = 60 such numbers.
There are 5 numbers of 1 digit, 25 numbers of 2 digits, and 75 numbers of 3 digits. This makes 105 numbers in all.

Assuming all 45 digits are different (which they will not be if they are ordinary integers), then 456, if repetitions are allowed. That is 8303765625. If repetitions are not allowed then the number falls to 45*44*43*42*41*40 = 5864443200
Allowing repetitions, there are 9 combinations. Without repeated digits, there is only one combination of 3 digits from 3.

27 three digit numbers from the digits 3, 5, 7 including repetitions.

24 three digit numbers if repetition of digits is not allowed. 4P3 = 24.If repetition of digits is allowed then we have:For 3 repetitions, 4 three digit numbers.For 2 repetitions, 36 three digit numbers.So we have a total of 64 three digit numbers if repetition of digits is allowed.

To determine the number of numbers that can be formed using the digits 1, 2, 3, 4, 5, and 6 without repetitions and less than 500, we first consider the hundreds place. Since the number has to be less than 500, the hundreds place can only be filled with 1, 2, or 3. For the tens and units place, any of the remaining digits can be used. Therefore, there are 3 choices for the hundreds place, 4 choices for the tens place, and 3 choices for the units place, giving a total of 3 x 4 x 3 = 36 numbers that can be formed.
Because in our system of numbers 100,000 is greater than 99,999.
It is possible to create a 3-digit number, without repeated digits so the probability is 1.
