Looking over my daughter's homework, I had a question that seems best to be asked here. It's from Everyday Mathematics (Volume 1, Grade 5, p 42.)
Tim flipped a coin 10 times. It landed heads up 7 times and tails up 3 times. Tim said, "I'll flip it 4 more times to get the same number of heads and tails." Is he right? Explain why or why not.
My gut tells me the new 4 flips will be 50/50 yielding 2 heads and 2 tails and won't take into account the previous flips. However, maybe they all land on heads giving a 50/50 overall distribution. Am I letting my knowledge of the Monty Hall Problem confuse me?
