Question 8.114

1. When we toss a coin, experience shows that the probability (long-term proportion) of a head is close to . Suppose now that we toss the coin repeatedly until we get a head. What is the probability that the first head comes up in an odd number of tosses (1, 3, 5, and so on)? Use the Probability applet to estimate this probability. Set the probability of heads to 0.5. Toss coins one at a time until the first head appears. Do this 50 times (click “Reset” after each trial). What is your estimate of the probability that the first head appears on an odd toss?
