  1. Hint: For continuous data, to find the probability that 0 &lt; X &lt; 1/2,

    you integrate over the bounds given, such that:

    1/2

    ∫ (3/8)x² dx

    0

    = [3/8 * 1/3 x³] from 0 to 1/2

    = 3/24x³

    = [3/24 *(1/2³) - 0]

    = 3/192  &lt;~~ This is P(0&lt; X &lt;1/2)

    Now, find P(1&lt; X &lt; 2) and think about the definition of ∪

    I hope this helps a bit.
