ganeshie8 (ganeshie8):
we can use a direct formula :
P(A or B) = P(A) + P(B) - P(A and B)

ok im with ya so far
ganeshie8 (ganeshie8):
` P(marinara) = 0.74, P(pesto) = 0.62, and P(marinara or pesto) = 0.90. Determine the P(marinara and pesto).`
P(marinara or pesto) = P(marinara) + P(pesto) - P(marinara and pesto)
ganeshie8 (ganeshie8):
plugin the given values :
0.90 = 0.74 + 0.62 - P(marinara and pesto)
ganeshie8 (ganeshie8):
P(marinara and pesto) = 0.74 + 0.62 - 0.90
