Answer:

(E) 29.0

Step-by-step explanation:

If a tag is drawn at random from each box, the expected value of the sum of the tags is the sum of the expected values for each tag.

The expected value for each tag is the mean value of the numbers in its box.

$EV = \frac{1+2+3+4+5+6+7+8+9+10}{10} +\frac{20+21+22+23+24+25+26+27}{8} \\EV = 5.5 +23.5\\EV= 29$

The expected value of the sum of the numbers on the two selected tags is 29.
