Jamal performed an experiment flipping a coin. He did 10 trials and then his arm got tired. He recorded his results in the table. Based on the experimental probability, Jamal predicted that the number of times the coin lands heads up will always be greater than the number of times it lands tails up. What is the error in his prediction?

Answer:
The error was that he said the number of times the coin lands heads up would ALWAYS be greater than the number of times it landed tails.
Explanation:
The fact that in his experiment the number of heads were greater than the number of tails does not mean it would always be like that. Someone else could carry out the same experiment and get different results. He should beware of using the word always.
