No, because either it's got an infinite number of zeroes or an infinite
number of ones.  Neither expansion is normal (they contain exactly none
of the other digit), and you can't include both simultaneously. 
Furthermore, normality or non-normality can only be properties of normal
numbers, and both of these expansions terminate or repeat, meaning that
they are rational, not irrational.  So therefore the normal/non-normal
qualification can't apply at all.
