(a)[2]
Mia chooses one triangle at random, records its properties and puts it back. Find the probability that it has line symmetry.
(b)[2]
Mia chooses one of the 25 shapes at random, notes its properties and puts it back. She then chooses a second shape at random, notes its properties and puts it back. Find the probability that both shapes are quadrilaterals.
(c)[3]
Mia picks three of the 25 shapes at random without replacement. Find the probability that just one of the shapes is a triangle with line symmetry.
