WebAdditive Principle. The additive principle states that if event A can occur in m ways, and event B can occur in n disjoint ways, then the event “ A or B ” can occur in m + n ways. 🔗. It is important that the events be disjoint: i.e., that there is no way for A and B to both happen at the same time. For example, a standard deck of 52 ... WebOct 17, 2024 · Your theory is that for some reason you multiply the exponents and add two, giving 6. But the divisors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, 36, which is nine divisors. Where did the reasoning go wrong? By enumerating the cases your technique counts you can see which three you missed and why. – Eric Lippert Oct 17, 2024 at 20:44

WebLet n be a positive integer. Then find the number of divisors of 210 n that are odd multiples of 3. Then answer must be in terms of n. My attempt: We have 210 = 2 × 3 × 5 × 7. The odd multiples of 3 dividing 210 are 3, 15, 21, 105. Let x be the odd divisor of n. WebApr 29, 2024 · Input : n = 24 Output : 8 Divisors are 1, 2, 3, 4, 6, 8 12 and 24. Recommended: Please try your approach on {IDE} first, before moving on to the solution. We have discussed different approaches for printing all divisors ( here and here ). Here the task is simpler, we need to count divisors. boneshire brewery harrisburg
