the principle is defined by the equation

p² + 2pq + q² = 1

where the frequency of the dominant allele is p, and the frequency of the recessive allele is q. Going by the what is given which is for the carriers is 0.04 = 2pq

substitute the value into the expression

p² + 0.04  +  q² = 1;  The information is not enough to calculate either p or q going by the equation generated.
