There are 60 science student in ss3 in a secondary school, 35 of whom studied chemistry, 30 studied technical dtawing, 12 of those student studied biology and chemistry, 10 studied chemistry but neither biology nor technical drawing, 11 only studied technical drawing, 10 also studied chemistry and technical drawing only
(a)how many student studied all 3 subjects
(b) how many student studied biology and technical drawing
(c)How many studied biology only
(d)draw a Venn diagram to illustrate the information
4 answers
I need the answer urgently
Draw your Venn diagram. If
x studied all three
y studied only Tech & Biology
z studied only Biology
then
10+22-x = 35
11+10+y = 30
32-x+y+z = 60
Solve those, and then you can fill in the rest of the Venn diagram and answer the questions.
