How many positive integers less than 1000 are there having each digit distinct and odd?

odd, even, even: 5 · 5 · 4 = 100 Case 3. even, odd, even: 4 · 5 · 4 = 80 Case 4. even, even, even: 4 · 4 · 3 = 48 The total number of even 3-digit integers with distinct digits is 100+100+80+48 = 328. So the total number of even integers less than 1000 with distinct digits is 4 + 41 + 328 = 373.

How many positive integers less than 10000 are?

How many positive integers less than 1000 A are divisible by 7 B are divisible by 7 but not by 11 C are divisible by both 7 and 11 d are divisible by either 7 or 11?

Step-by-step explanation: ==> The number of positive integers divisible by 7 but not by 11 is 142 – 12 = 130. ==>the number of positive integers less than 1000 that are divisible by either 7 or 11 is 142 + 90 – 12 = 220.
