Since there are 10 cards and each card has an equal chance of being selected, the probability of selecting number 5 is 1/10.
Expected value = probability of event x number of trials
Expected number of times 5 will be selected = (1/10) x 120 = 12.
Therefore, you can expect to select number 5 12 times out of 120 trials.
