Typically, the values of Z offered in tabulated form are positive values only,
though you may have Z given as positive and negative.
If you only have a positive list, then you use the symmetry of the normal curve to write
P(Z>-1.05) is the same value as P(Z<1.05).
So what is P(Z<-1.05) ?
Your next step is to realise that you must subtract the probability of
P(Z<-1.05) from P(Z<1.10) to find the probability you are looking for.
So, ask yourself "What is P(Z<-1.05) in terms of the positive Z values ?".
Hint: The area under the Standard Normal curve is 1, so P(Z<x) + P(z>x) = 1,
since all probabilities of a situation sum to 1.
P(-1.05<Z<1.1) is the difference between P(z<1.1) and P(z<-1.05).
You should get clear about that first.
If so, then you may be able to conclude the final value of the probability
I should have asked if you were able to make some progress with this initially,
or if you didn't know where to start
