  1. P(sum=5) :
    The favourable outcomes  ={(3,2),(1,4)}
    Number of favorable outcomes  =2
      Probability of getting a sum 5 =P(sum=5)=236=1/18

  2. let s be the total number of sample space

    if two diced are rolled then the total number of sample space n(s)=6²=36

    sample spaces when the sum on the dice is 5

    n(B)= { (1,4),(2,3),(3,2),(4,1)} = 4
    P(B)=n(B) / n(S)

    =4/36

    =1/9
