a. Zero percent
b. Fifty percent
Explanation:
As it has been mentioned in the question that both man and woman are normally pigmented and each one have an albino parent thus both will be heterozygous and their allelic makeup will be as follows -
Man - Aa
Woman - Aa
After a cross between Aa × Aa we get the following result-
One AA, Two Aa and One aa
It is clear that only the aa type of offsprings will be albino. 
Out of 4 there is probability of only one to be albino so out of two there will be 50% probability of being albino.
The probability of both sons to be albino will be zero percent.
