🎲 Dice: Two Dice – Probability of a Sum of 7
  • Task:
  • When two dice are rolled simultaneously, calculate the probability that the sum of the dice is exactly 7.
  • Step-by-step Solution:
    1. Determine possible pairs: The pairs \(1,6\), \(2,5\), \(3,4\), \(4,3\), \(5,2\), \(6,1\) yield a sum of 7.
    2. Number of favorable outcomes: There are 6 favorable combinations.
    3. Total number of possible outcomes: Each die has 6 sides → 6 × 6 = 36 possible combinations.
    4. Calculate probability: 6 favorable cases / 36 total cases = \( \frac{1}{6} \).
  • Answer:
  • The probability of rolling a sum of 7 with two dice is 1/6.
