Answer

Using the given probabilities, we have: P(B|C) = $\frac{P(B and C)}{P(C)}$ = $\frac{0.05}{0.2}$ = 0.25 P(C|B) = $\frac{P(B and C)}{P(B)}$ = $\frac{0.05}{0.4}$ = 0.125

Work Step by Step

Using the given probabilities, we have: P(B|C) = $\frac{P(B and C)}{P(C)}$ = $\frac{0.05}{0.2}$ = 0.25 P(C|B) = $\frac{P(B and C)}{P(B)}$ = $\frac{0.05}{0.4}$ = 0.125
