One difference between a binomial random variable x and a standard normal random variable z is that with the binomial random variable we cannot determine P(x = a), while for the standard normal variable we can determine P(z = a).

This statement is false. We can determine P(x=a) for a binomial random variable using the binomial probability formula. However, we cannot determine P(z=a) for a standard normal variable since the probability at a specific point is always zero in a continuous distribution.
