How do I calculate the probability as requested below? Can you provide the formula using the data provided? Not just the formula without numbers (P (Z<1.55) but the actual calculation i.e. what number is Z? And then how do we calculate it?

Given a standardized normal distribution (with a mean of 0 and a standard deviation of 1), complete parts (a) through (d).

a. What is the probability that Z is less than 1.55?

The probability that Z is less than 1.55 is ______.
