Out of 16 spins, a purple-and-red spinner landed on purple 9 times and on red 7 times. Based on experimental probability, how many of the next 64 spins would you expect on land on red? A: 28 B: 29 C: 30 D: 36

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
