    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?
    A 208 Correct Answer Incorrect Answer
    B 234 Correct Answer Incorrect Answer
    C 250 Correct Answer Incorrect Answer
    D 264 Correct Answer Incorrect Answer

    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
