Question
If the winning probability is 0.3, then the probability of losing a game is______.
- 0.3
- 0.4
- 0.7
- 0.8
Hint:
Probability of an event = Number of favourable outcome / Total number of outcomes
The correct answer is: 0.7
Here, it is given that the probability of winning a game is 0.3.
We have to find the probability of losing the game.
We know, P(E) + P(not E) = 1
So, P(winning a game) +P(losing a game) = 1
Or, P(losing a game) = 1 - P(winning a game)
Or, P(losing a game) = 1 - 0.3
= 0.7
Hence, the correct option is (c).
0 ≤ P(E) ≤ 1 , sum of probabilities of all events = 1
