Question

If the probability of winning a game is 0.7, what is the probability of losing it?

Answer 1

The probability of either losing or winning the game is 1 as any one thing must happen.

Probability of losing or winning the game
=P(w)+P(l)
P(w)= probability of winning the game
P(l)= probability of losing the game.
P(w)=0.7
P(w)+P(l)=1
0.7+P(l)=1
P(l)=0.3
