    Answer: 0.267

    Step-by-step explanation:

    The probability when she checks social website first = 4/6

    Now, she is left with 5 webistes out of which two are school-related so probability = 2/5

    So, the probability when she checks social webiste first and school related website later = 4/6 x 2/5

    Probability = 0.267
