Question

How many numbers less than 1000 can be made from digits 123456?

Answer 1

Answer:

There are 85 numbers

Step-by-step explanation:

That means the number would be a three digit number and less, therefore

Since there’s no repetition of digits

The first digit can be pick in in 5 ways

The second can be picked in 4 ways

And the third can be picked in 3 ways

=5*4*3=60 three digit numbers

For two digits we have them picked in 5*4=20 two digit numbers

And single digits would be picked in 5 ways= 5 single digit number

Therefore the total numbers lesser than 1000 that could be formed = 60+20+5=85 numbers
