Answer 2

Answer:

a) 8  b(i)) 19/55  b(ii)) 28/55

Step-by-step explanation:

To get the answer to B you add all of the numbers in the venn diagram which gives you 47 and then you subtract that from the overall number of students which gives you 8.

To find the number of students who passed french and german you take the number from the middle of the diagram (19) and put it out of the overall number of students which is 55 and so the answer is 19/55

To find the number of students that passed exactly one of these two subjects you put 17/55 (those who passed french) and 11/55 (those who passed german) and then you add them together which gives you 28/55.
