Peter Winkler's books of mathematical puzzles ("Mathematical Puzzles" and "Mathematical Mind-Benders") are top-notch and highly recommended. You will learn something there even if you've read dozens of puzzle books before.
彼得·温克勒在《数学谜题》中分享了该问题的一些精彩变体：“周二出生的男孩”（第 xix 页）和“有姐妹的男人”（第 xxii 页）。“钱斯夫人有两个不同年龄的孩子。其中至少有一个是周二出生的男孩。请问两个孩子都是男孩的概率是多少？”（注意：这是一个谜题，不是生物学或人口统计学……
Peter Winkler shares some great variations of this: "Boy Born on Tuesday" (p. xix) and "Men with Sisters" (p. xxii) in "Mathematical Puzzles". "Mrs. Chance has two children of different ages. At least one of them is a boy born on Tuesday. What is the probability that both of them are boys?" (note: it is a puzzle, not a biology or data demography…
Where can I find more of these? Do you guys recommend this author's books such as https://www.amazon.com/Mathematical-Puzzles-Connoisseurs-Pet... ? (It's hard to find the right search term for this that doesn't return a lot of non-mathematical brainteasers or stuff aimed at kids)
彼得·温克勒的数学谜题集（《数学谜题》和《数学动脑筋》）都是顶级的，强烈推荐。即便你之前读过几十本谜题书，也照样能从中学到新东西。
