1. 1/15
2. 12/15
3. 11/15
4. 13/15
5. 14/15

Answer 1

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
