[2 marks Question 54
The Venn diagram in Figure 1 shows the number of students in a class who read any of 3 popular magazines A, B and
C.

One of these students is selected at random.
Given that the student reads at least one of the magazines, find the probability that the student reads C.​

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

a triangular prism is a 3 dimensional shape composed of triangles and rectangles. it is made from two triangular bases and three rectangular sides.  

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
