Question

Angelina's Italian Restaurant has collected data about customer sauce orders. It calculated that P(pesto) = 0.42, P(alfredo) = 0.86, and P(pesto or alfredo) = 0.93. Determine the P(pesto and alfredo).

A 0.35

B 0.07

C 0.51

D 0.23

Answer 1

\[\large P(p \cup a)=P(p)+P(a)-P(p \cap a)\]
Plugging in the given values, we get:
\[\large 0.93=0.42+0.86-P(p \cap a)\ .........(1)\]
Now you just need to solve (1) to find P(pesto and alfredo).
