Which I never learnt how to solve in high school back then, I'm ashamed of it...

Hi, what about this: a deck of 40 cards contains 23 blue and 17 red cards. I randomly pick up 7 cards. What are the odds:

1 - I take zero red cards;

2 - I take exactly three red cards;

3 - I take exactly seven cards?

Thanks
