You need to be more precise about what you are asking, what you have posted is meaningless.

In the standard normal distribution the area under the density curve between Z=+/- 1.96 is 0.95, ans the area under the curve beyond Z=1.96 is 0.025.

Once you have made clear what you are asking for it will just require a table look-up, exactly how depends on the exact form of your normal distribution table.
