Answer 2

Answer: 0.557

===================================================

Work Shown:

$P(A \cap B) = P(A) + P(B) - P(A \cup B)\\\\P(A \cap B) = 0.78 + 0.65 - 0.873\\\\P(A \cap B) = 0.557$

Side note:

A similar formula is $P(A \cup B) = P(A) + P(B) - P(A \cap B)$

We can isolate the last term to get the first equation shown above.
