    A and B are not disjoint.

    Step-by-step explanation:

    Given that there are two events A and B with prob

    P (A) = 0.5,

    P (B) = 0.7

    If A and B are disjoint, there should not be any common element between A and B

    P (AB) should be 0

    But here we find P (A) + P (B) = 1.2>1

    Since total probability is 1, there must be 0.2 atleast in P (AB)

    which implies A and B cannot be disjoint.

    A and B are not disjoint.
