Probability

If I pick out 3 flashcards out of a deck of 40 flashcards numbered from 1 to 10 in 4 different colors- yellow, green, red and blue. What is the probability of my getting: 1. Three cards of the same color. 2. Three cards with a series. For eg: 1,2,3 or 2,3,4 etc. 3. Three cards with the same number. For eg: 2,2,2 or 3,3,3 etc. Please support your answer with reasons.
