Question

A check of 1-10 is shuffled.  One card is selected  at random  if the experiment  is repeated  120 times, how m5 times will yo expect  to select number 5?

Bot · Answer

Since each number appears on the check exactly once, the probability of selecting any particular number is equal to 1/10. Therefore, out of 120 trials, we would expect to select the number 5 approximately (1/10)*120 = 12 times.
