The Lottery Problem – Solved

We had the following riddle. Assume there are 2 different types of lottery. Lotto A makes you choose 6 numbers out of a possible 75,and lotto B where you choose 5 numbers out of a possible 60 and 1 ‘mega’ number out of a possible 40. Which lottery gives you the best odds?

How to find a prime

Last week we talked about what a prime number is, but we didn’t talk about a good way of finding what number is prime and what is not [other than checking if any number less than p divides that number]. This area of finding out what number is prime has been a big problem for many mathematicians and still has a lot of unanswered questions. The world of mathematics is still looking for an easy way to calculate whether a number is prime or not with a simple formula.

Prime Numbers

A prime number by definition is a number p>1 such that p has no positive integer divisors other than 1 and p.

Wait… What?

Monty Hall Problem – Solved

Before the holidays I posted a question to you all to get your opinions. The question posed regarded the famous Monty Hall problem in which there are 3 doors and are told 1 has a fabulous present while the other 2 have goats. You select a random door and the host reveals one of the doors that have a goat and gives you a chance to switch doors if you want or not. The question was: is it better to keep the original door, switch doors, or are the odds the same?

Triangles – Fun Fact

Fun fact! In the real world, if you take a triangle and add up the angles, they can equal more than 180 degrees.

Modulo

Modulo! Mod you who? Modulo: A complicated way to say remainder!

Infinity

Say you have an infinite number of camels walking through the desert and a little baby camel is born, how many camels are there now? Surely there are still an infinite number, and surely since we added 1 more camel this infinity is greater than the original infinity. But is it even possible for infinity to be greater than infinity? So confusing!
