The probability of $A$ occurring is $0.05$. The probability of $B$ occurring is $0.20$. How many times more likely is $B$ to occur than $A$?
My immediate intuitive response was $4$, but evidently that can't be correct, as that would be implying that an event with $100\%$ likelihood is $20$ times more likely than $A$. Although this question might sound rather trivial, I'm not sure how to go about finding the answer.
