Question

probability help?!



I suck at probability and everything in AFM. I got some questions down, but I got a few more to go. I would take help on any of them.
-what is the probability of rolling a 2 and then an odd number on two dice?
-two cards are drawn at random. what is the probability that they will be either 2 red cards or 2 jacks?
-a jar contains 7 blue coins and 6 red, in how many ways can 2 blue and 2 red be chosen?

Answer 1

1/6 * 1/2 ?
1/2*25/26 + 4/52*3/52
not sure for this one but
Pred*Pblue= 6!/2!4! *7!/2!5!

Answer 2

remember that OR is +
AND is *
