Hi all,

I trying to solve this probability question:

Its a about a lottery game.

I choose 7 different numbers from range of 1 to 70.
The lottery directors choose 17 different numbers from the range of 1 to 70.

What are the chances that all of the 7 numbers I chose are included within the 17 numbers the Directors chose?

Remark: A number cannot be chosen more than once. I mean, after I chose my first number, I have to pick up more 6 numbers out of the 69 left etc... and so about the directors, after they chose their first number, they have to pick up more 16 numbers from the 69 numbers left etc...

Thanks.
