Suppose 37% of all adults have some college education. Define the following events: S = a US adult is a stockholder C = a US adult has some college education State two marginal and one conditional probability. P(S) = .43, P(C) = .75, P(C|S) = .37 P(S) = .43, P(C) = .37, P(C and S) = .75 P(S) = .43, P(C|S) = .75, P(C) = .37 P(S) = .43, P(S|C) = .75, P(C) = .37

43% of all adults are stockholders

75% of stockholders are college educated.

OPtion c is right

since P(S) = 0.43 and P(C) = 0.37 and P(C/S) = 0.75
