Answer:

  1 : 4

Step-by-step explanation:

You want the odds in favor of an event with a probability of 1/5.

Odds

The odds in favor of an event with probability p are ...

  p : (1 -p)

Here, that is ...

  1/5 : (1 -1/5) = (1/5) : (4/5) = 1 : 4

The odds in favor of choosing a red marble are 1 : 4.
