  2. Arranging the data in ascending order: 4.97, 4.98, 5.00. 5.03, 5.04, 5.05, 5.06, 5.07, 5.08,
    Total number of flour bang = 11 and number of bags containing more than 5 kg of flour = 7
    Therefore,
    P(A bag contains more than 5 kg of flour) = 7/11
    Hence, the probality that any of these bags chosen at random contains more than 5 kg of flour is 7/11.
