Explanation / Answer
i) P(beer | male) = P(beer and male) / P(male)
= [62/500] / [217/500]
= 62/217
= 0.2857
j) P(beer | female) = P(beer and female) / P(female)
= [25/500] / [283/500]
= 25/283
= 0.0883
k) P(femalec | wine) = P(male | wine)
= P(male and wine) / P(wine)
= [31/500] / [105/500]
= 31/105
= 0.2952
