A simulation uses cards numbers zero through nine to generate a 2-digit numbers a card is selected four the tens digit and not replaced then a card for the ones digit is drawn and not replaced the process is repeated Intel all the cards are used if you simulate if the simulation is performed 10 times about how many times could you expect a two digit number to begin with five

Mitchell Trevino · Answer 1

The probability that the 5 will end up as a 10s digit (not a 1s digit) is 1/2. Thus, about half of the experiments are expected to result in a 2-digit number that begins with 5.

If the experiment is performed 10 times, the expected number of times a 2-digit number begins with 5 is 5.
