    The probability that a randomly selected consumer will recognize Amazon is 0.988.

    Step-by-step explanation:

    The data given in the question is

    Total number of consumers = 795 + 10 = 805

    Consumers who knew of Amazon = 795

    Consumers who did not know of Amazon = 10

    The formula for calculating probability of an event A is:

    P (A) = No. of favourable outcomes/Total no. of possible outcomes

    P (Recognize Amazon) = No. of Consumers who knew Amazon/Total no. of consumers

    P (Recognize Amazon) = 795/805

    = 0.98757

    P (Recognize Amazon) ≅ 0.988

    The probability that a randomly selected consumer will recognize Amazon is 0.988.
