Surely the question you ask is not the one you meant to ask; P(D given D) is 1.

The logical probability to ask for is P(D given C); I will assume that is what you wanted.

P(C|D) = (P(C and D)) / (P(D))
0.6 = P(C and D) / 0.5
P(C and D) = 0.3

Then

P(D|C) = (P(C and D)) / (P(C))
P(D|C) = 0.3 / 0.4
P(D|C) = 0.75

ANSWER: P(D given C) = 0.75
