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

Answer 1

Since there are 10 cards labeled 1-10 and each card has an equal chance of being selected, the probability of selecting number 5 is 1/10 or 0.1.

If the experiment is repeated 120 times, we can expect to select number 5 approximately 120 * 0.1 = 12 times.
