To find the probability that a student who likes shopping also likes cooking, we use the formula for conditional probability:
P(Likes Cooking | Likes Shopping) = P(Likes Cooking and Likes Shopping) / P(Likes Shopping)
From the table:
P(Likes Cooking and Likes Shopping) = 40
P(Likes Shopping) = 57
Therefore, P(Likes Cooking | Likes Shopping) = 40/57 ≈ 0.7018
So, the probability that a student who likes shopping also likes cooking is approximately 70.2%.
Therefore, the answer is 70.2%
