To find the probability that a student does not like pies given that they do not like sandwiches, you need to use the number of students who do not like sandwiches and do not like pies, which is 6, divided by the total number of students who do not like sandwiches, which is 32.
Probability = 6/32 = 0.1875
Convert this to a percentage by multiplying by 100:
0.1875 x 100 = 18.75%
Therefore, the probability that a student does not like pies given that they do not like sandwiches is 18.8%.
