Help plzzz!!Given P(A) = 0.78, P(B) = 0.65 and P(AUB) = 0.873, find the value of
P(An B), rounding to the nearest thousandth, if necessary.

Help plzzzGiven PA 078 PB 065 and PAUB 0873 find the value of PAn B rounding to the nearest thousandth if necessary class=

Answer: 0.557

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

Work Shown:

[tex]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\\\\[/tex]

Side note:

A similar formula is [tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]

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