Question

Brianna rolls two number cubes labeled 1–6. What is the probability that Brianna rolls a sum of 5?

Answer 1

Answer:
`(1)/(9)`

Explanation:

Given

Brianna roll two cubes labeled 1-6

To get a sum of 5, sample space is

`n(s)=\{(1,4),(4,1),(2,3),(3,2)\}`

No of the elements in
`n(s)` is 4

The total outcomes possible is 36

`\therefore \text{Probability }P=(4)/(36)\\\Rightarrow (1)/(9)`
