What is the probability of rolling any pair of numbers with two dice? Let’s first solve this and then confirm our calculated probability by simulating 500 dice rolls with a spreadsheet! In this post, we will focus on understanding basic probability concepts and then discover how with spreadsheets, we can actually see whether our calculated probability holds true!

Coin-flipping Life Experiment

What if life’s major choices are to be decided by the flip of a coin? Interestingly, the Freakonomics Experiments project – a collaboration between Freakonomics and the University of Chicago –  is enlisting volunteers to do just that to study human behavior of decision-making. Intriguing, right?

An essential feature of this experiment is generating a truly random toin coss. While the Freakonomics Experiments team ensured coin toss randomness by using the Swiss-based Fourmilab’s True Random Number Generator (more info here), we can create our own coin toss using spreadsheets!  Really? You bet!
