Answer:

a) 4 students studied the three sciences.

b) Number of students who studied Physics = 17

c) Number of students that studied Biology or Chemistry or both = 30

Number of students in total = 36

Step-by-step explanation:

Using the Venn diagram, the region where the three circles of Biology, Chemistry and Physics denotes number of students that studied the three subjects.

Therefore,

a) 4 students studied the three sciences.

b) Number of students who studied Physics

= sum of all the numbers inside the circle of Physics

= 1 + 4 + 4 + 8

= 17

c) Number of students that studied Biology or Chemistry or both = sum of all the figures insides the circle of both Biology and Chemistry

= 1 + 3 + 4 + 5 + 8 + 9

= 30

d) Number of students in total = summation all the figures inside the diagram

= 4 + 5 + 9 + 1 + 3 + 8 + 4 + 2

= 36
