Nanna's Italian Restaurant has collected data about customer sauce orders. It calculated that P(marinara) = 0.64, P(alfredo) = 0
.56, and P(marinara or alfredo) = 0.89. Determine the P(marinara and alfredo).
1 answer:
To answer this question, apply this formula <span>P(m and a) = P(m) + P(a) - P(m or a). Where m stands for marinara and a stands for alfredo.
</span><span>P(m and a) = P(m) + P(a) - P(m or a)
</span><span>P(m and a) = 0.64 + 0.56 - 0.89
</span><span>P(m and a) = 0.31</span>
