We can expect to roll the number 5 a total of 50 times (in 400 attempts).
We assume that all the numbers in the die have the same probability of being rolled up.
Then the probability of rolling a 5 is one over the number of sides of the die, this is:
p = 1/8
Then out of these 400 times, we can expect to roll a 5 1/8 of the times, so we get:
400*(1/8) = 50
We can expect to roll a 5 around 50 times.
