Answer:
Step-by-step explanation:
The normal distribution curve standard is bell shaped having mean =0 and std devition =1.
This is symmetrical about the y axis i.e. mean.  More than 99% of the area under the curve lie between z=-3 to z=3
To find the area to the right of z =0.05 is equivalent to 
calculating the 
Probability that Z >0.05
= P(Z>0.05) 
=0.5-0.0199
=0.4801
