Card game probability question

I've not done probability in a while and looking at online examples I don't know if I'm doing everything right so maybe you can can help me out with the formula and explanation.

I'm a big fan of the game Magic the Gathering and when playing the game I like a healthy number of "land" cards in my opening hand. There are 60 cards in my deck and 26 land cards I've put in. What is the probability I will have 3 land cards in my opening hand (7 cards)? What about 2 land cards? What about atleast 2 land cards? Thanks in advance.
