Let E be an event of winning the game, then E' will be losing it.
P(E) + P(E') = 1
⇒ 0.7 + P(E') = 1
⇒ P(E') = 0.3
Hence, the probability of losing the game is 0.3.

The sum of probabilities of all the outcomes of an experiment is one.

The probability of a sure event is one.

The probability of a possible but not a sure event lies between zero and one.

The probability of an impossible event is zero.

For any event E, P(E) + P(not E) = one.
