Re: probability



2nd question:
what is the probabilty of obtaining either tails or heads in 5 tosses of a fair coin?
They say 1/2
I think probability = 1


That is the correct answer to the question as worded. I do not agree that the question is gibberish, though it may seem silly. Actually, I don't even think it is silly.

I am appalled at the wrong answers in the key to the exam. Apparently, the author of the exam meant to write different questions.
