  2. $\dfrac{1}{6}$
  3. $\dfrac{2}{6}$
  4. $\dfrac{7}{6}$

A Correct answer
Explanation

There are 6 doubles out of 36 possible outcomes (1,1 to 6,6). The probability of getting a double is 6/36 = 1/6. The probability of not getting a double is 1 - 1/6 = 5/6.

AI explanation

When rolling a pair of dice, there are 36 possible outcomes. A double occurs when both dice show the same number, which gives 6 outcomes: (1,1), (2,2), (3,3), (4,4), (5,5), and (6,6). Using the complementary probability rule, the probability of not getting a double is 1 minus (6/36), which equals 30/36 or 5/6.
