Concept:Probability $= \dfrac{\text{number of favourable outcomes}}{\text{total number of outcomes}}$.Given:10 green balls, 8 white ballsSolution:Total number of balls $= 10 + 8 = 18$Favourable outcomes (green) $= 10$$P(\text{green}) = \dfrac{10}{18}$Divide top and bottom by 2: $\dfrac{5}{9}$Key point: $\dfrac{4}{9} = \dfrac{8}{18}$ is the probability of white. Divide by the total (18), not by the number of white balls.Answer:Option C ($\dfrac{5}{9}$)
