Chapter CSB1.13, Problem 8E

To determine

The probability that coin land in the rug.

Answer to Problem 8E

Probability will be equal to 0.3

Explanation of Solution

Given :

Dimension of square patio is 10 feet by 10 feet.

Dimension of rectangular rug is 5 feet by 6 feet.

Area of square patio is equal to,

  $\begin{array}{l}A=10\times 10\\ =100{\text{ ft}}^2\end{array}$

And area of rectangular rug is equal to,

  $\begin{array}{l}{A}_{rug}=5\times 6\\ =30{\text{ ft}}^2\end{array}$

Probability is given by ratio of favorable case to total case.

Therefore,

  $\begin{array}{l}p=\frac{A_{rug}}{A}\\ =\frac{30}{100}\\ =0.3\end{array}$
