Answer 1

1 sum on top face is prime no is 15/36=5/12

2 .sum on both faces is13 is 0

3.doubletis 6/36=1/6

4.both faces have composite no. is21/36

Answer 2

1) favorable out comes =(1,1) (2,1) (1,2) (4,1)(3,2)(2,3) (1,4) (6,1) (5,2) (4,3) (3,4) (2,5) (1,6) (6,5) (5,6)
probability= 15/36
2) probability= 0
3)favorable outcomes = (1,1) (2,2) (3,3) (4,4) (5,5) (6,6)
probability= 6/36
4) probability=21/36(except prime numbers)
