A deck of 10 cards labeled 1-10 is shuffled. One card is selected at random. If the experiment is repeated 120 times, how many times will you expect to select number 5?
A. 10
B. 12
C. 1/120
D. 1/10
B. 12
Since each card has an equal probability of being selected, you would expect to select each number 5 out of the 120 times with the same probability. Therefore, you would expect to select the number 5 12 times out of the 120 trials.
