Probability is (desired outcomes)/(total possible outcomes)
ok, you must make a choice 1. if you believe that 1 is prime (which I don't) go to AAAAAAAAAAA 2. if you believe that 1 is NOT prime, go to BBBBBBBBBBB
AAAAAAAAAAAA prime numbers from 1 to 6 are 1,2,3,5 desired outcomes=4 total possible =6 4/6=2/3
BBBBBBBBB prime numbers from 1 to 6 are 2,3,5 3 desired outcomes 6 total possible
3/6=1/2
if you belive that 1 is prime, then 2/3 is probability if you believe that 1 is NOT prime then 1/2 is probability
