Answer 1

Part A:

Like pasta Do not like pasta Total

Like rice 10 30 40

Do not like rice 20 40 60

Total 30 70

100

Part B: When we look at the table above, we can see that 40 people do not like rice or pasta, so 40 out of 100 = 40%, so 40% of the people surveyed don't like either.

Part C: People surveyed have a greater dislike for pasta than rice. Reason: 60 people do not like rice and 70 people do not like pasta, and 70>60 so people dislike pasta more.

Answer 2

Base from the given the given, out of 100 customer, 30 people who liked pasta, 10 liked rice also. There were 40 people who like rice. Meaning, there are only 20 people who like rice alone, 30 people who like pasta alone and 10 people who like both pasta and rice. Since it is not given, it can be assumed that 50 people don’t like pasta nor rice.
