Chapter 10, Problem 22CR

To determine

To find:The probability of odd square number.

Answer to Problem 22CR

  $\text{probability=}\frac{1}{2}=50\%$

Explanation of Solution

Given information: A ten sided solid whose identical faces are numbered with the first ten square numbers.

Calculation: First ten square numbers are $1,4,9,16,25,36,49,64,81,100$

  $\begin{array}{l}\text{Therefore sample space={ 1,4,9,16,25,36,49,64,81,100 }}\\ \text{ Total outcomes=10}\\ \text{odd square numbers=5}\\ \text{ probability(odd square number)=}\frac{5}{10}=\frac{1}{2}\\ \text{ in percentage=}\frac{\text{1}}{\text{2}}\text{×100=50\%}\\ \text{ Equally likely }\\ \\ \end{array}$
