I don't know joint probability. But you can get the answer by multiplying the numbers together.

I don't know much about cards (can you tell me how many picture cards and how many color cards are there in a deck)

Are you serious you don't know? There are Jacks, Queens and Kings (picture), Ace's, 2-10's. Four of each.
