Since the probability of the coin landing leads is 1/2, simply cube 1/2 to arrive at your answer: 1/8.
You cube 1/2 because you must land heads three times in a row and each flip is independent from other flips.
You have: y=0.73x+1. Compare this to the equation of a straight line (in slope-intercept form). The slope, m, is 0.73. The y-intercept, b, is 1.
Transitive.
Associative is (a + b) + c = a + (b + c)
Commutative is a + b = b + a
Reflexive is a = a
Thus, transitive is the correct answer.
Hope this helps!
