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 time will you expect to select the number 5?

1 answer

Since each card has an equal probability of being selected (1/10), we can expect to select the number 5 approximately 1/10 of the time.

Therefore, out of 120 repetitions, we can expect to select the number 5 approximately 120 * 1/10 = 12 times.
