Correct Answer – Option 5 : 14/15
Given
Total numbers = 15
Formula used
P(E) = Number of favourable outcomes/Total number of outcomes
Calculation
Let E is an event of winning a game
Total outcomes = 15 × 15
⇒ 225
Number of favorable outcomes (winning a game) = 15
P(E) = 15/225
⇒ 1/15
Probability of not winning a game = 1 – (1/15)
⇒ 14/15
