To find the expected number of times you would select the card labeled "5" when drawing from a shuffled deck of 10 cards (labeled 1 to 10) over 120 trials, you can use the concept of expected value.
The probability of selecting the card labeled "5" in one trial is:
\[ P(5) = \frac{1}{10} \]
Now, to find the expected number of times you will select the card "5" in 120 trials, you multiply the probability by the number of trials:
\[ \text{Expected value} = P(5) \times \text{Number of trials} = \frac{1}{10} \times 120 = 12 \]
Therefore, the expected number of times you will select the number "5" is:
12
So the correct response is 12.
