An ordinary, fair sided dice is rolled 480 times. How many times is the number 3 expected?

An ordinary dice has six sides. We have an equal chance to roll on any of these six sides. This gives us the probability of rolling a 3 (or any other number) as 1/6.Each roll is independent i.e the result of one roll does not influence the result of any other roll.So to get the number of times we expect to get a 3, we multiply the number of times we roll the dice with the probability of us getting a 3:480*1/6 = 80
