There are 6 equally likely outcomes . Because theres one of each number . 6 being the highest and 1 being the lowest .


( E ) If you roll the die once, what is the probability of rolling a 3 ?


The probability of rolling a 3 would be . P(3) = 1/6 . = 16.6%


( H ) If you roll the die 60 times, about how many times would you expect to get a 1 ?


You would get a 1 . About 10 times .


( I ) If you roll the die 300 times , about how many times would you expect to get a five .
