Question

how many six digit even numbers are possible if the left digit cannot be zero

Answer 1

That's an interesting question. What's the only thing that matters when you're looking if a number is odd or even?

Answer 2

the last number

Answer 3

i think the answer is 450,000

Answer 4

exactly, because you have 9 possibilities for the first number, then 10 for the next 4 and 5 for the last, which gives you, as you found 9*10000*5

Answer 5
