# A die is thrown repeatedly until a six comes up. What is the sample space for this experiment?

**Solution:**

In this experiment, six could come back either in the first throw, the second throw, the third throw, or until six is obtained.

Hence, the sample space of this experiment is given by

S = {6, (1, 6), (2, 6), (3, 6), (4, 6), (5, 6), (1, 1, 6), (1, 2, 6), .... , (1, 5, 6),

(2, 1, 6), (2, 2, 6), .... , (2,5, 6), ...., (5, 1, 6), (5, 2, 6), ....}
