As David said the probability of receiving a free pass is 1/5 but if you are actually looking for the "odds" of it happening it would be 1 to 4 or 1:4 in favor of it happening.

Yes, thank you, Arnold. I misread. The odds are 1:4.

Hello Arnold! I had a question about understanding odds compared to probability. I'm thinking of ratios as more of 1 part per 4 parts, but there are a total of 5 parts (chemistry reasoning is coming through). Would the thinking be along the same lines, so that 1 event per 4 would be event A, but there are 5 events total?

Yes, odds are like the ratio of parts to parts. Probability is the ratio of part to the whole.
