Given that P(A) = 0.54 and P(B) = 0.21 and P(A and B) = 0.15, determine if the events A and B are independent.

• Yes. (0.54)(0.21) does not equal 0.15 which means the events A and B are independent.

• Yes, P(A and B) is not zero so the events must be independent.

• No. P(A and B) = 0.15 which is not zero so the events are not independent.

• No. (0.54)(0.21) = (0.1134) which does not equal the stated value of P(A and B) which means A and B are not independent.
