Asked by Samantha
Hi, I don't understand a homework question, can anyone please help me? I'm bad at probability.
what is the probability that when you pick two cards, you will select at least one king out of two in a deck of six standard cards? (assuming there are no jokers)

I just don't understand how to start it, I need structure , I can figure out the rest, don't know how to get into a strategy.

there are 4 kings in 52 cards, so the chance of picking a king on the 1st draw is 4/52 = 1/13
Now there are only 51 cards, with 3 kings left. SO, the chance of picking a king on the 2nd draw is 3/51 = 1/17
So, the chance of picking two kings in a row is 1/13 * 1/17 = 1/221
No idea what a "deck of six standard cards" is.
If I have misunderstood the question, apply the logic above to the real problem.
