Vedclass · Answer

(A) Total number of balls in the box $= 5 + 8 + 4 = 17$.Therefore,the total number of elementary outcomes in the experiment of drawing a ball from the box $= 17$.Let event $C$ be the event that the ball drawn is not green.Let event $\overline{C}$ be the event that the ball drawn is green.There are $4$ green balls in the box.Therefore,the number of outcomes favourable to event $\overline{C} = 4$.Thus,$P(\overline{C}) = \frac{4}{17}$.Using the property of complementary events,$P(C) = 1 - P(\overline{C})$.Therefore,$P(C) = 1 - \frac{4}{17} = \frac{17 - 4}{17} = \frac{13}{17}$.
