Answer:
27/54
Step-by-step explanation:
Let the no. of white blue and black marbles be 3x , x and 2x respectively.
Now, 3x+x+2x= 6x
54 =6x
54/6= X
Therefore X= 9
Therefore,. No.of blue marbles= X= 9
No.of black marbles = 2x
=2×9 =18
Total no of marbles that are not white = 18+9= 27
Hence, Probablity of a marble which is not white = 27/54
= 1/2
Hope it helps.
