To find the expected number of times you would select the number 5 when drawing from a deck of 10 cards labeled 1 to 10, you can use the concept of probability.
The probability of selecting the number 5 in one draw is:
\[ P(\text{selecting 5}) = \frac{1}{10} \]
If you repeat this experiment 120 times, the expected number of times you would select the number 5 can be calculated by multiplying the probability of selecting 5 by the number of trials:
\[ \text{Expected number of times selecting 5} = P(\text{selecting 5}) \times \text{number of trials} \]
\[ \text{Expected number of times selecting 5} = \frac{1}{10} \times 120 = 12 \]
Thus, the answer is:
B) 12
