Question

When two dice are rolled simultaneously find the probability of the following event s
Event A= the sum of the digit on the upper face is 6 .

Answer 1

Answer:

P(S)=1

Step-by-step explanation:

S={(1,1),(1,2),(1,3),(1,4),(1,5),(1,6),

(2,1),(2,2),(2,3),(2,4),(2,5),(2,6),

(3,1),(3,2),(3,3),(3,4),(3,5),(3,6),

(4,1),(4,2),(4,3),(4,4),(4,5),(4,6),

(5,1),(5,2),(5,3),(5,4),(5,5),(5,6)

(6,1),(6,2),(6,3),(6,4),(6,5),(6,6)} n(S)=36

A={(1,5),(2,4),(3,3),(4,2),(5,1)} n(A)=5

P(S)=n(S)/n(S)=36/36=1

P(A)=n(A)/n(S)=5/36
