Papa's Italian Restaurant has collected data about customer sauce orders. It calculated that P(marinara) = 0.74, P(pesto) = 0.62, and P(marinara or pesto) = 0.90. Determine the P(marinara and pesto).

A. 0.12

B. 0.46

C. 0.16

D. 0.22

Answer 1

I think it is B.

Answer 2

B is correct! :)

Answer 3

\(P(A \cap B) = P(A)+P(B)- P(A \cup B)\)

Answer 4

yay! :D thanks! :D

My work:
0.9 = 0.74 + 0.62 - P(marinara and pesto)

0.9 = 1.36 - P(marinara and pesto)

P(marinara and pesto) = 1.36 - 0.9
= 0.46

Does that looks right?

Answer 5

absolutely :)

Answer 6

thanks so much! :D
