The outcome of the second roll is independent from the previous outcome. The probability of getting any given number from 1 to 6 is always the same: 1/6.

Therefore, the answers are:

a) The probability that the second roll is also a 4 is 1/6.

b) The probability that the second roll is a 1 is 1/6.
