Question
The probability of selecting a rotten egg randomly from
a basket of 1000 eggs is 0.16. What is the number of rotten eggs in the basket?Solution
Total number of eggs in the basket = n(S) = 1000 Let E be the event of selecting a rotten egg from the basket. Number of outcomes favourable to E = n(E) P(E) = n(E)/n(S) 0.16 = n(E)/1000 ⇒ n(E) = 1000 × 0.16 ⇒ n(E) = 160 Therefore, the number of rotten eggs in the basket = 160
