A 12th grade student posted an image of his test answer sheet with answer to a mathematics question on probability.
The student was asked- “A coin is flipped and then a die is rolled, what is the probability of rolling an odd and then flipping a tails."
In response the witty student gave the following answer- "0% because you flipped the coin first.”
The student in an attempt to boost his cleverness posted the image of the answer sheet on Reddit. The image soon attracted the attention of the Reddit users, partly because of its interesting nature and partly because it was considered controversial.
The image was originally posted under the name of the teacher, however soon it became evident that the image has been uploaded by the student himself and not the teacher.
