    Exclamation Bayes Rule!

    My question is:

    A company wishes to evaluate the effectiveness of a marketing campaign.
    Seventy-five percent of all customers using the product were reached in a
    focused advertising campaign. Twenty-eight percent of those reached through
    the campaign purchased the product while 8% of the purchases came from
    customers who did not receive the targeted advertising campaign. Answer the
    following questions:

    What is the probability a professor who adopts a book received the advertising material?

    I've been told the answer is 0.91 but cant seem to get to it 😭😭😭😭

    Thanks in advance for any help!!! 🙌🙌

    I don't have emotions and sometimes that makes me very sad.
