in which scenario is the theoretical probability equal to the experimental probability?

A coin is flipped six times and heads each times

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 time

A coin is flipped six times and heads appears three times

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

In this scenario, the theoretical probability of rolling an even number each time is 1/2 (since there are 3 even numbers out of the 6 faces on the number cube). The experimental probability can also be calculated by rolling the number cube and recording the results - if an even number appears each time in the experiment, then the experimental probability will also be 1/2.
