There are two fathers and two sons.
Three apples were shared between them and they get one each.

How is that possible?

A pupil wants to investigate a report that Begian one euro coins are biased in favour of heads.

Here is the plan for the investigation:

I will spin 20 Belgian one euro coins to give one set of results. I will do this 10 times to give a total of 200 results to work out an estimated probability of spinning a head. If this probability is greater than 56% my conclusion will be that Belgian one euro coins are biased in favour of heads.

The table shows the ten sets of results:

Number of each set of 20 coins than showed heads.

10  13  11      11  12 12 11 9 10   

Using the pupils plan, what should her conclusion be?

You must show your working plzz

Thanks Bye
