Los Angeles Math Circle

1/20 -- Junior Circle: Math Kangaroo preparation plus Monty Hall Paradox. (Nadya Kuzkina)

For the first 70 min. of the class, the students will be given a Math Kangaroo test for 5th and 6th graders from one of the years passed. Even if your child doesn't plan to take part in the actual Math Kangaroo competition this year, it's very beneficial to solve the problems, they are non-trivial and fun! After a 5 min. break, we will run a simulation of the Monty Hall Paradox. Please see the following URL for more. http://en.wikipedia.org/wiki/Monty_Hall_problem It is possibly the most famous paradox of elementary probability theory. To make it more striking, we will use ten doors (or rather playing cards) instead of only three from the original version.
