You start by getting a friend or family member to put 2 different coloured objects (e.g: I used buttons ) in different number sums. All together adding up to 6 in total. Then draw out of the bag as many times as you want, writing down how many of each you have pulled out. When you are ready to guess which colour has the most objects. If you ask your friend or family member which colour you think has the most, and you are correct, good job, you have just predicted correctly without knowing what was inside.
The first time I tried it I drew from the bag 8 times. I pulled out 5 blue buttons and 3 black.
So I decided to make a prediction. I guessed that there were more blue than black and was wrong.
The next time I played I drew 20 times and pulled out 6 black and 14 blue. I guessed blue and was right.
I learned that to properly predict you have got to try a decent amount of times.
Hi Cooper
ReplyDeleteGreat blog about the probability maths game! I liked how you played the game more than once to check if the prediction of the probability was accurate or a one off. This is a good measure for working this out, well done. Have you tried any other probability games such as with a dice and predicting if you will throw a six?

Thanks for sharing this blog post Cooper.You explained what you did well and it was a great start to our probability work . I'm glad to hear you persevered with more than one attempt at this game ....go you!!! What other games are you familiar with that involve making predictions or guessing?
