If I choose a number between 1 and 10000, what is the probability that I will pick a even number that isn’t divisible by 7?

First step is to find how many 7s there are!

There are: 4,286 numbers between 1 and 10,000 inclusive that are even and not divisible by 7.

 

The probability is =4,286 / 10,000 =2,143 / 5,000
