Simulation: Toss a coin

# Simululation: Toss a Coin # Toss a coin 5000 times; after each toss, calculate the ratio of heads to all tosses. # Graph the ratio against time; the X axis is the toss number, the Y axis is the ratio of heads to all tosses at that point in time. # Lauri Ruotsalainen, 2010 import random @interact def coin(n = input_box(default=5000, label="Number of Tosses"), interval = range_slider(vmin=0.0, vmax=1.0, default=(0.47, 0.53), step_size=0.01, label="Plotting range (y)")): c = [] k = 0 for i in range(1, n): k += random.randint(0, 1) c.append((i, k/i)) show(point(c, gridlines=[None, [0.5]], pointsize=1), ymin=interval[0], ymax=interval[1])
