You can multiply in any order if it's all multiplication.
So you can do (4.5*6)*(10^-8*10^-4)
which equals 27*10^-12

Written in scientific notation is 2.7 * 10^-11 (Since you moved decimal one back, you don't have to move it again in the exponent, hence it becomes 10^-11)
D. is the answer

<h2>Solution</h2>

A <em>conditional relative frequency table</em> shows the relative frequencies determined upon a row or column.

There are two types of relative conditional frequency table: 1) row conditional relative frequency, and 2) column conditional relative frequency.

When you divide the joint frequency by the marginal frequency of the column total you have the row conditional frequency table. When you dividethe joint frequency by the row total you have the colum conditional frequency table.

In a row conditional relative frequency each total of the right hand column equals 1. This is the case of the second table.

In a column conditional relative frequency each total of the bottom row equals 1. This is not happening with any of the shown tables.

Hence, only the second table could be a conditional relative frequency table.
