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?(1 point

Since there are 10 cards total and only 1 of them is number 5, the probability of selecting number 5 is Start Fraction 1 over 10 End Fraction for each trial.
To find the expected number of times number 5 will be selected in 120 trials, you would multiply the probability by the number of trials:
Start Fraction 1 over 10 End Fraction * 120 = 12
Therefore, you would expect to select number 5 12 times in 120 trials.
