Question
The probability of selecting a rotten egg randomly from
a basket of 800 eggs is 0.26. What is the number of rotten eggs in the basket?Solution
Total number of eggs in the basket = n(S) = 800 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) 0.26 = n(E)/800 ⇒ n(E) = 800 × 0.26 ⇒ n(E) = 208 Therefore, the number of rotten eggs in the basket = 208
