In which scenario is the theoretical probability equal to the expected probability?

A coin is flipped six times and heads appears each time.

A number cube is rolled six times and an even number appears each time.

A number cube is rolled six times and a 6 appears four times.

A coin is flipped six times and heads appears three times.

In the second scenario where a number cube is rolled six times and an even number appears each time. This is because the theoretical probability of rolling an even number on a fair number cube is 1/2, and the expected probability of rolling an even number on each of the six rolls is also 1/2.
