Q13 of 78 Page 939

A box contain 150 orange is taken out from the box at random and the probability of its being rotten is 0.06 then find the number of good orange in the box.

Total no. of Oranges = 150


Probability of rotten oranges =0.06


∴ Probability of good oranges = 1 – 0.06 = 0.94


⇒ (no. of good oranges)/(no. of total oranges) = 0.94


⇒ no. of good oranges = 0.94 × 150 = 141


Thus, the number of good orange in the box = 141
