Solution

`7/9`

Explanation:

Total possible outcomes = Total number of marbles

                                       = ( 3 + 2 + 4) = 9 

Let E be the event of not getting a white marble.

It means the marble can be either blue or red but not white.

Number of favourable outcomes =  (3 + 4) = 7 marbles
