Solve a. 1.2(3x - 5) = 1.5(2.4x - 4)
b. 1/4(20 - 4a) = 6 - a
c. 4(d + 2) = 14 - 2(3 - 2d)
d. 3/8(x + 4/9) = -5/16(2x + 4/5)
e. 2[5(w + 3) - (w + 1)] = 3(1 + w)

Which of these numbers of simulations of an event would be most likely to produce results that are closest to those predicted by probability theory? 15, 20, 5, 10
