Chapter 0.5, Problem 10E

To determine

To find: Experimental odds against rolling 1 or a 6 and then find the experimental odds in favor of rolling a number less than 3.

Answer to Problem 10E

  $4:1$ and $1:2$

Explanation of Solution

Given information:

The result of rolling a die 120 times is shown below:

  

Calculation:

There were 96 rolls that were not a 1 or a 6. The remaining 24 rolls were a 1 or a 6.

So, it would be $96:24$ , which on simplify gives $4:1$ .

A total of 40 rolls were less than 3. The remaining 80 rolls were equal to or higher than 3.

So, we get $40:80$ , which on simplifying gives $1:2$ .
