Question:** Two fair six-sided dice are rolled. What is the probability that the product of the two numbers is a prime number?

["Probability That the Product of Two Dice Rolls Is a Prime Number", "When two fair six-sided dice are rolled, each die shows a number from 1 to 6, resulting in a total of (6 \ imes 6 = 36) possible outcomes. Many players wonder: What is the probability that the product of the two numbers rolled is a prime number? Understanding this probability involves analyzing prime number properties and examining all relevant combinations.", "### What Makes a Product a Prime Number?", "A prime number is defined as a natural number greater than 1 that has no positive divisors other than 1 and itself. For the product of two dice rolls (let’s call them (a) and (b)) to be prime, one of the following must hold:", "- One die shows a 1 (since multiplying any number by 1 yields that number), and the other die shows a prime number (since prime × 1 = prime).\n- The other number must be 1, and the first number a prime.", "Note: The product of two integers greater than 1 cannot be prime—because it would then have at least three divisors: 1, itself, and the smaller prime number, which violates the definition of a prime.", "Prime numbers between 2 and 36 (the possible dice product range) are:\n2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31", "But since dice only show values 1 through 6, the only prime values achievable in the product are: 2, 3, and 5. (7 and higher prime numbers would require at least one die roll greater than 6 to be achievable, which is impossible with standard dice.)", "### When Is the Product a Prime?", "The product (a \ imes b) is prime only if one die is 1 and the other is a prime number. So valid pairs are:", "- (1, 2) → product = 2\n- (1, 3) → product = 3\n- (1, 5) → product = 5\n- (2, 1) → product = 2\n- (3, 1) → product = 3\n- (5, 1) → product = 5", "These are the only favorable outcomes where the product is prime.", "Let’s count them:", "- (1,2), (2,1) → 2 outcomes\n- (1,3), (3,1) → 2 outcomes\n- (1,5), (5,1) → 2 outcomes", "Total favorable outcomes = 6", "### Calculating the Probability", "Total possible outcomes when rolling two dice:\n(6 \ imes 6 = 36)", "Favorable outcomes: 6", "Thus, the probability is:", "[\n\frac{6}{36} = \frac{1}{6}\n]", "### Summary", "- Dice show numbers 1–6.\n- Product is prime only if the result is one of: 2, 3, or 5.\n- This occurs only when one die is 1 and the other is a prime (2, 3, or 5).\n- There are exactly 6 such outcomes among 36 total.\n- Probability = ( \frac{1}{6} )", "Understanding dice probability helps not only in games but also in concepts like probability distributions, independence, and prime number identification.
