    U means union - that is the union of the 2 sets A and B which are illustrated by the circles

    So it wants me to find what A + B is minus the center?

    A has \(.3\) and B has \(.35\) and they have \(.10\) in common that means \[A\cup B=0.30+0.35-0.10\]

    the center is called \(A\cap B\) reads "A intersect B"

    .55 is the answer then, I believe. Thanks a bunch :)
