Beau Berry · Answer 1

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.
