The table shows the probabilities of the results. Drink coffee Do not drink coffee Total Drink water 0.3 0.24 0.54 Do not drink water 0.25 0.21 0.46 Total 0.55 0.45 1.00 Let A represent drinking coffee and B represent drinking water. Which statement is true? Drinking coffee and drinking water are not independent events because P(A|B)=P(A) and P(B|A)=P(B). Drinking coffee and drinking water are independent events because P(A|B)=P(A)and P(B|A)=P(B). Drinking coffee and drinking water are independent events because P(A|B)≠P(A) and P(B|A)≠P(B) . Drinking coffee and drinking water are not independent events because P(A|B)≠P(A)and P(B|A)≠P(B).
