  1. I suggest you make a table of sums for 6 rows and 6 columns from the numbers from 1 to 6
    Fill in the sums, e.g. the first row and last row would be
    2 3 4 5 6 7
    7 8 9 10 11 12

    count up all the odd ones, obviously 18 of them
    Remember 2 is a prime number so it must be included as well
    All other primes would be odd, and are already counted.
    so prob(of your event) = 19/36
