Q8 of 98 Page 686

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

Let E be the event of winning the game

P(E) + P(not E)= 1 where P(E) denotes probability of occurrence E and P(not E) denotes probability of non-occurrence of E


∴ Then, P (losing the game) = P (not E) = 1- 0.7 = 0.3
