I feel the phrase "more likely than not" is often seen or heard here and there, sometimes in a sentence, other times just the phrase alone like the following ones.
"More likely than not" a COVID-19 vaccine is possible, Fauci tells Senate
More Likely Than Not? This is Scientific?
I am now curious about:
How likely is it for you in percentage terms? (My perception is somewhere between 51% and 55%)
Is there any phrase describing exactly the opposite, which implies a probability level of around 46% to 49%, for example? Any such phrase especially in a similar word combination like "less likely than xxxxx", if any?
