1.	If the probability of winning a game is 0.7, what is the probability of losing it?
Answer» Given that probability of winning a game is 0.7 = P(A) (Let) We know that for a game, there are only two possibility losing and winning. Let the probability of losing the game is P(B). We know that, the sum of probabilities for all possible outcomes is equal to 1. ∴ P(A) + P(B) = 1 ⇒ P(B) = 1 – P(A) = 1– 0.7 = 0.3. (∵ P(A) = 0.7) Hence, the probability of losing the game is 0.3.

Given that probability of winning a game is 0.7 = P(A) (Let) We know that for a game, there are only two possibility losing and winning.

Let the probability of losing the game is P(B).

We know that, the sum of probabilities for all possible outcomes is equal to 1.

∴ P(A) + P(B) = 1

⇒ P(B) = 1 – P(A) = 1– 0.7 = 0.3. (∵ P(A) = 0.7)

Hence, the probability of losing the game is 0.3.
