Fred can't make a decision so he decides to flip a coin. However, he is reluctant to have his fate dependant on a mere flip of a coin (because he is stupid). He decides to flip the coin 10 times and go with the majority. He then starts thinking; which of the two methods would give me a better 50:50 chance?

A. Flip a coin once
B. Flip a coin 10 times
C. It doesn't matter; the chances are equal with both methods

Fred needs help.

Smart people do not decide questions by flipping coins; although I like the I-Ching!

just answer the question, I did mention that he was stupid

what are you afraid of? Someone please answer the question.

A, because in B there is a chance of 63/256 of a tie.

As has been stated, flip the coin an odd number of times to avoid a tie. A collection of N honest 50:50 results will have a statistical error of sqrt(N). 100 flips wll have a 10% error rate. 10,000 flips will have a 1% error rate.

Make a decision based on even or odd. See how many people attended a racetrack that day. There is your answer, such as it is.

thanks! Stupid questions sure get some great answers.
