Question

How many four-digit odd numbers less than 6000 can be formed using the digits 2, 3, 4, 5, 6, and 8?

Answer 1

288

Explanation:

First position choice: 4 numbers

Second 6 numbers

Third 6

Fourth 6

TOTAL 4 digit numbers 4 * 6 * 6 * 6 = 864 combos

2 out of 6 of these will end in 3 or 5 (thus making an odd number)

864 * 2/6 = 288 such numbers
