    Answer:

    The approximate probability that she checked a social website first and then a school-related website is 0.267.

    Step-by-step explanation:

    Given that a student wants to check six websites, and four of the websites are social and two are school-related, and after checking just two sites, she has to leave for school, to determine what is the approximate probability that she checked a social website first, then a school-related website, the following calculation should be performed:

    4/6 x 2/5 = X

    0.26666666 = X

    Therefore, the approximate probability that she checked a social website first and then a school-related website is 0.267.
