Answer:
Probability =
Step-by-step explanation:
Length of segment AD = 12 units
Since, AC = CD
Therefore, AC = CD = = 6 units
Since, AB = BC
Therefore, AB = BC = = 3 units
Number of total segments = 5
Number of segments having measure greater than three = 3
(AC = CD = 6 units and AD = 12 units)
Probability that the measure of a segment is greater than 3
=
=
