Answer 1

Answer: Check out the screenshot below for the answers

==========================================================

Step-by-step explanation:

For each column, we divide the values by the sum of each column.

The sum of the first column is 6+8 = 14, and the sum of the second column is 7+3 = 10.

Column 1:

• 6/14 = 0.43
• 8/14 = 0.57

Those values are approximate to two decimal places.

Column 2:

• 7/10 = 0.70
• 3/10 = 0.30

Those values are exact.

The values in bold are then filled in the table as you see below.

A result like 0.43 means that 43% of those who play a sport also play an instrument. The other values are interpreted in a similar fashion.
