Solution

Total number of possible outcomes = 10+16+8=34 balls 

n(s)=34 

Favorable outcomes for not a red ball= favourable outcomes for white or green ball 

Number of favorable outcome for white or green ball=16+8=24=n(E) 

Probability for not drawing a red ball =`(n(E))/(n(s))=24/34=12/17` 

  Is there an error in this question or solution?
