It seems the image you've shared isn't visible. Could you please describe the problem in text (e.g., the question, any given conditions, or details about what needs to be calculated)? This way, I can assist you effectively.

If you're referring to a common problem (like arranging letters, counting permutations/combinations, etc.), feel free to type out the problem statement, and I'll provide a step-by-step solution. For example, if it's a problem like "How many ways to arrange the letters of 'MATHEMATICS' such that no two vowels are adjacent?", I can walk through the process. Just share the details!

Let me know the exact problem, and I'll help solve it.
