Are events A and B independent? 4.18 If P(A and B) = 0.4 and P(B) = 0.8‚ find P(A | B). ½ = 0.5. 4.19 If P(A) = 0.7‚ P(B) = 0.6‚ and A and B are independent‚ find P(A and B). 4.20 If P(A) = 0.3‚ P(B) = 0.4‚ and P(A and B) = 0.2‚ are A and B independent? Because P(A and B) = 0.20 and P(A)P(B) = 0.12‚ events A and B are not independent. Applying the Concepts 4.21
