Short Answer

The table shows sales in thousands of units of iPods^(R) , Powerbooks^(R) and iMac^(R) in the fourth quarter of 2001. $$\begin{array} { | l | l | l | l | } \hline & \text { iPods } ^ { ( \mathbf { R } ) } & \text { Powerbooks } ^ { ( \mathbf { R } ) } & \text { iMac } ^ { ( \mathbf { R } ) } \\\hline \text { Units } ( \mathbf { 1 } , \mathbf { 0 0 0 } ) & 1,040 & 230 & 240 \\\hline\end{array}$$ ​
Compute the probability that the item sold in 2001 Q4 was either the PowerBooks^(R) or the iMac^(R) .
Round to two decimal places, if necessary.
The probability is __________.
