Answer:

Total balls = 5 + 6 + 7= 18. The selected ball should not be white hence it should be from any of 5 green or 6 black balls = (6+5)=11 balls.

\bold{AnsweR:}

\bold{\frac{11}{18} }  

Step-by-step explanation:

Total balls = 5 + 6 + 7= 18.

The event of Selecting a ball at random from 18 balls = 18 C 1 =18

The selected ball should not be white hence it should be from any of 5 green or 6 black balls = (6+5)=11 balls.

Hence event of 1 ball to be selected from 11 balls = 11 C 1. = 11

Probability that ball is not white=

Selecting any ball other than white / Total selection

= \large\boxed{\mathfrak{\frac{11}{18} }}}
