Sample space

All possible outcomes of an experiment. Examples: One coin, two coins, one die, two dice.

Tutorial on sample space

For tossing the coin: H,T

For one dice: 1,2,3,4,5,6

For two die:
(1,1),(1,2),(1,3),(1,4),(1,5),(1,6).
(2,1),(2,2),(2,3),(2,4),(2,5),(2,6).
(3,1),(3,2),(3,3),(3,4),(3,5),(3,6).
(4,1),(4,2),(4,3),(4,4),(4,5),(4,6).
(5,1),(5,2),(5,3),(5,4),(5,5),(5,6).
(6,1),(6,2),(6,3),(6,4),(6,5),(6,6).

Tutorial on probability

Let's do lots of experiments:
