It looks like you've uploaded a PDF. Let me take a look at it and extract the relevant mathematical content for you. PyPDF2 import PdfReader

Load the uploaded PDF

pdf_path = "/mnt/data/173799278359080oqdlv7.pdf" reader = PdfReader(pdf_path)

Extract text from all pages

pdf_text = '' for page in reader.pages: pdf_text += page.extract_text()

Display the extracted text for analysis

pdf_text[:1500] # Show the first 1500 characters to inspect the contentIt seems the extracted text from the PDF is not entirely clean, possibly due to formatting or encoding issues. However, I can still detect some mathematical problems and questions related to probability and events. Here's a summary of some of the content:

1. Several problems concerning conditional probability and events $A$ and $B$ (likely related to a probability space).
2. Questions involving calculations related to certain experiments or events.
3. Some proofs are requested regarding the relationships between different events.

Would you like me to extract a specific section or help with solving one of the problems mentioned? Feel free to clarify or ask for more details!
