Correct answer: (A) 1/61/6

Explanation

There are 36 equally likely outcomes, and a sum of 7 comes from (1,6), (2,5), (3,4), (4,3), (5,2), (6,1), i.e. 6 outcomes. Probability = 6/36 = 1/6.36 समसम्भाव्य परिणाम हैं, और योग 7 (1,6), (2,5), (3,4), (4,3), (5,2), (6,1) से आता है, अर्थात् 6 परिणाम। प्रायिकता = 6/36 = 1/6।
