Two dice are thrown simultaneously the probability of obtaining a total score of 5 is

A

`(1)/(9)`

B

`(1)/(18)`

C

`(1)/(36)`

D

`(1)/(12)`

Text Solution

Verified by Experts

The correct Answer is:
A

Total number of elements in sample space of throwing two dice, `n(S)=36`
Let E = Event of getting a score of 5
`= {(1,4),(4,1),(2,3),(3,2)} rArr n(E )=4`
`therefore P(E )=(n(E ))/(n(S))=(4)/(36)=(1)/(9)`
