Chapter 5: Q 8. (page 294)

Keep on tossing The figure below shows the results of two different sets of 5000coin tosses. Explain what this graph says about chance behavior in the short run and the long run.

Short Answer

Expert verified

The probability of getting ahead is around a third of the time0.5

Step by step solution

01

Step 1. Given Information  

We must explain what this graph implies about chance behavior in the short and long term using the figure, which illustrates the results of two different sets of5000 coin tosses.

02

Step 2. Concept Used   

A probability is a number between 0(never occurs) and 1(always occurs).

03

Step 3. Explanation   

This graph explains how chance behaves in the short and long term. As we can see, in the short run, the result can vary greatly and take on values that are considerably different from a proportion of 0.5While the graph shows that the proportion always tends to be around 0.5in the long run, this means that the long-term relative frequency is about 0.5and so the probability of heads will be around 0.5
