A compsite number is a number that is NOT prime technically 1 is not prime since the definition is divisible by 1 and itself 2 is prime 3 is prime 4 is not prime 5 is prime 6 is not prime
2 solutions for 2 different views: A: 1 is prime B: 1 is not prime
A: 1 is prime so we have 1,2,3,5 are prime and 5 and 6 are not probablity is (desired outcomes)/(total possible outcomes) desired outcomes=2 (5 and 6) total possible outcomes=6 (6 numbers on cube) 2/6=1/3=0.33 probabiligy is 0.33
B: 1 is not prime if 1 is not prime then we have 2,3,5 as prime and 1,4,6 as not prime probability is (desired outcomes)/(total possible outcomes) desired outcomes=3 (1,4,6) total posible outcomes=6 (6 faces on cube) 3/6=1/2=0.5 the probability is 0.5
