Answer 2

`P(Not\ 3) = (5)/(6)`

Explanation:

Given

`S = \{1,2,3,4,5,6\}` --- sample space

Required

P(not 3)

First, we list out all outcomes that are not 3.

We have:

`Not\ 3 = \{1,2,4,5,6\}` --- 5 possible outcomes

`S = \{1,2,3,4,5,6\}` ---- 6 total outcomes

So, P(Not 3) is calculated as:

`P(Not\ 3) = (n(Not\ 3))/(n(S))`

`P(Not\ 3) = (5)/(6)`
