"Chance Encounters"

Miranda's description: How to Play the Game

1. First you need to choose a box and tell us which one it is.
2. Then you must try to roll the marble into that house.
3. If you get the marble into the house you chose, you get a point.

The chances of winning were meant to be 25% but our game was more skill than probability, because you didn't always roll the ball into a house. The probability of winning was more than 50%.

What happened during the fair: at 8.45 the children started playing our games. At first many people were losing but after a while we kept on having to give out stickers. Most children went away happy, which made me happy. About half way through the fair someone walked away with our marble so we had to get another one. When we saw the children's cards with three checks, we always made sure that they had a sticker.

Jules's description: The theoretical probablity of winning our game was 25%. When we actuallyhad the fair the experimental probability was 64%.

The first thing we had to do was set up our game. At 8.45 people came to play our game. At 9.00 the small children came - they were so cute! 160 people won at our game and 102 people lost at our game. At 10.30 we each got to play our own games and other people's games. Miranda left me to look after our booth while she went round to play other people's games so I didn't get to play any games. But I got stickers any way! Mrs Verkerk dsaid we could have some.
