How many even five digit whole numbers are there?
To find the number of even five-digit whole numbers, we first note that a five-digit number ranges from 10,000 to 99,999. The last digit must be even, which can be 0, 2, 4, 6, or 8 (5 options). The first digit can be any digit from 1 to 9 (9 options), and the three middle digits can each be any digit from 0 to 9 (10 options each). Thus, the total number of even five-digit whole numbers is (9 \times 10 \times 10 \times 10 \times 5 = 450,000).
