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

Options

A. `(1)/(9)`
B. `(1)/(18)`
C. `(1)/(36)`
D. `(1)/(12)`

Answer

A

Explanation

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)`
