If 12 fair coins are flipped once, what is the probability of a result as extreme as or more extreme than 10 heads? (Note, "as o
r more extreme than" means in *either* direction -- that is to say, as or more extreme both in terms of getting that many or more heads, and in terms of getting that many or more tails.)
the question is: why should ppl answer your questions correctly and help you when you dont answer thier questions and help them when they need it? why help some one who wont help you?
