In 2021, 101 members of the UK Parliament were asked "If you toss a fair coin twice, what is the probability of getting two heads?" The answer is, of course, 1/4 or 25%. FWIW, only 52% of the MPs got the answer correct.
However, this is an improvement from 2011, when only 40% of the MPs got the answer correct.
First immediate thought: What would be the result if we asked US Congressmen the same question?
Second immediate thought: If that many legislators don't understand such a basic principle of high school math, are they qualified to be making big policy decisions that affect all our lives?
