Students tested a Belgian one Euro coin over 250 trials. What did they find?
AHeads came up 44 percent of the time
BHeads and tails each came up 50 percent
CHeads came up 56 percent of the time
DHeads came up 67 percent of the time
Answer & Solution
Correct answer: C. Heads came up 56 percent of the time
1. Two professors in Europe had their students run 250 trials with the coin.
2. Heads came up 56 percent of the time and tails 44 percent.
3. That split suggests the coin is not fair, though more repetitions would be needed to be sure.
4. The figure of 44 percent is the tail share, so quoting it for heads reverses the result.
