PROBABILITY: A GRADUATE COURSE

Toss a symmetric coin twice. What is the probability that both tosses will yield a head?

This is a well-known problem that anyone can solve. Namely, the probability of a head in each toss is 1/2, so the probability of two consecutive heads is 1/2 · 1/2 = 1/4.

BUT! What did we do? What is involved in the solution? What are the arguments behind our computations? Why did we multiply the two halves connected with each toss?
