Question

PLEASE HELP WITH ATTACHED PHOTO:)

I completed the Venn diagram but a, b and c need answering, I don’t think the completed Venn diagram is completed right though. So please correct me if needed :)

Answer 1

a. 0.69

b. 0.13

c.0.56

Explanation:

Total number = 100

a) either means students with either option are valid

69/100 = 0.69

b) both means each student has done both math and english

=13/100 = 0.13

c) Only one means has done one subject and not both classes. We have 23 for math and 33 for english (this is according to your venn diagram)

23+33=56

one subject =56/100 = 0.56
