Question

If two dice are rolled, what is the probability that the sum of the upturned faces will equal 5

Answer 1

Answer:

10 is the answer for sure

Answer 2

Answer:

1/4

Explanation:

s={ (1,1) ,(1,2),(13),(14),(15),(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) (4,5) ,(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)}

there for, n ( S) =36

suppose,

Event A: sum of upturned face will equal to 5

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

there for, n ( A) = 4

the probability of A = n ( A) /n(S)

= 4/36

= 2/8

= 1/4

There for, the probability or the sum of the upturned face will equal 5 is 1/4
