First the number of possible outcomes for two events is the product of the number of outcomes for each event....in this case:
number of outcomes=2*6=12 (because you have six number and heads and tails)
Now if you wanted to list out the possible outcomes...which is tedious and useless once you can find it as a product like done above...
h1, h2, h3, h4, h5, h6, t1, t2, t3, t4, t5, t6
