Empirical vs. Theoretical Probability

Imagine a bag with red blocks and blue blocks. You randomly draw 1 block, observe the color, and replace it in the bag. Repeat this until you have picked 10 blocks. This completes 1 trial of the experiment. The table below simulates 30 trials of the experiment. Column B shows the number of red blocks drawn over 10 picks. The graph shows how many trials resulted in the outcome (number of reds) shown on the horizontal axis.
