None of the provided options (1/6, 1/2, 1/3) match the correct probability of 7/12.

What is the probability of obtaining tails or a five?

Coin outcomes: Heads (H) or Tails (T)

Die outcomes: 1, 2, 3, 4, 5, or 6

Tails and any die outcome (1, 2, 3, 4, 5, or 6)

The favorable outcomes are Tails + 6 possibilities (T1, T2, T3, T4, T5, T6) + Heads + 1 possibility (H5).

Total possible outcomes are 2 (H or T) * 6 (die outcomes) = 12.

Therefore, the probability (P) of obtaining tails or a five is:

=1/2 + 1/6

=[6+1]/12

= 7/12

Therefore, none of the provided options (1/6, 1/2, 1/3) match the correct probability of 7/12.
