Which of the following cannot be the probability of an event?

Explanation

∵ The probability of any event is always between 0 and 1, i.e., positive. <table> <tr> <th>0 ≤ P (A) ≤ 1</th> </tr> </table> ∴ According to the question, The probability of any event cannot be negative (-0.7).

Your task: before EVERY markdown element you output (paragraph, heading, table, list, code block, mermaid block, image placeholder, equation, page_header, page_footer, etc.), insert an HTML comment listing the layout region id(s) that correspond to that element: Rules: - Every markdown element MUST be preceded by a comment. - A single element may map to multiple layout regions (e.g. a table spanning two detected regions). List all matching ids separated by spaces. - A layout region should appear in at most one comment. - Use the bounding box and label to match visual regions on the screenshot to the content you are transcribing. - If a visible region has no matching layout id, you can omit the attribution comment for that element. - The layout region table is a reference for attribution only — the OCR text content is provided separately. Tables: - Output tables in HTML when possible. - Table…
