A multiple choice question has 5 possible answers. What are the odds in favor of guessing the right answer? (1 point)

1:5
4:1
1:4
3:2

My answers:
1. 2/6
2. 5/6
3. 4/6
4. 1:5

Answer 1

in #1 - 3 you don't state what the event is, so those questions are incomplete

#4. Odds in favour of some event
= prob of the event / prob of not the event

prob of correct choice = 1/5

so the odds in favour of picking the right answer
= (1/5 / 4/5)
= 1/4
or 1 : 4
