Requirements: A coin for each student & smart board or data projector.
First ask your students to toss a coin 10 times each.
Ask each student how many heads in a row they threw.
Now ask students ‘Do you think it is possible to throw 10 heads in a row?
It can be done. Here is how you do it.
Derren Brown is a UK mentalist, magician, hypnotist and maths guru. He’s awesome. He shows audiences how a lack of understanding maths, especially probability, leads to misinterpreting the facts.
This is the most awesome way to introduce probability.
Mentalist Derren Brown devises a foolproof gambling system. He sends a girl , Kadisha, the number of a winning horse in race to be run the next day. It wins. He sends her the winning horse and race number 4 more times. She ends up with winnings close to £ 1000 before the final race. Derren convinces her to borrow money for the last bet. She does. She places £4,000 on a horse. Did it win?????
Watch Part 5 of The System
If you are not convinced Derren Brown can come up with a foolproof system for horse race tipping, let me explain The System. He took 7,776 e-mail addresses, divided them into 6 equal groups and sent each group a different number for a horse in a 6 horse race to be run the next day. Naturally, one group of 1296 had been given the winning horse number. This group was divided into 6 again and given the number of the ‘winning’ in a six horse race the next day and so on.
Race 1: 7776
Race 2: 1296
Race 3: 216
Race 4: 36
Race 5: 6
Out of 7776 punters, only one punter was given in advance five horse race winners in a row. Was it Kadisha. You will have to watch the Youtube above.
