How many elements are there in the sample space of rolling of two unbiased dice?

When three coins are tossed. Then how many number of elemens are there in the sample space of this event 4 7 9 8

For any two events A and B in a sample space

If one die is rolled once, then the sample space is

An experiment consists of rolling die until a 2 appears.(i)How many elements of the sample space correspond to the event that 2 appears on the k^(th) roll of the die? (ii)How many element of the sample space correspond to the event that 2 appears not later than the k^(th) roll of the die?

Two dice are thrown.Describe the sample space of this experiment.

Assertion : Two coins are tossed. Number of elements in the sample space is 4. Reason : When a coin is tossed n times then the number of elements in its sample space is n + 2.

Describe a sample space, if a die is thrown two times.
