Answer 2

Greater than 4 would be 5 and 6, so that is 2 numbers out of 6 total possible numbers.
The probability of is 2/6 which is 1/3.
If you roll it 1000 times, the probability of rolling greater than 4 would still be 1/3.
You do (1/3) * 1000, or 1000/3 to get expected number of times that you roll greater than 4.
