Answer 2

Answer:

Step-by-step explanation:

The larger the number of throws  the closer the results will be to the probability of a head.  That is for a fair coin it should be close to 50%.

With only 10 throws you could get a result not close to 50% but the coin could still be fair.

So Simon's results ( 100 throws)  would be more useful to decide if the coin is biased or not.
