How do I find five different rational numbers to represent 12%?



An unfair coin, with P(Heads) = 0.55 is flipped two times. It says draw a tree diagram for this and determine the probability that both flips yield the same result. I drew a tree diagram, but I don't know how to determine the probability. Can you tell me how to do this?



Finally, how do I find the probablity of picking a ten and a club, and picking a two or not a diamond from a deck of 52 cards? Hopefully, you can help me figure out these problems. I am having a hard time doing these.
