If a dice is rolled 300 times, what is the expected number of times a 5 will land face up?
Since we are assuming we are talking about a fair, six-sided die, the probability that a 5 will land face up is 1/6 each time. If we are rolling the die 300 times, we would expect a 5 to land face up 300*1/6 = 50 times.
