How do we find gene frequncy and geneotype frequencies of the th orignal sample?

the dominant gene T controls the ability to taste the chemical phenylthiocarbamide(PCT) Individual with the T allele frind (PCT) bitter while tt individuals find it tasteless. in a sample of 320 students at a local high school ,218 were tasters and 102 were non tasters. uming this is a random sample from the student body population, calculate the following: 1-GENE FREQUENCY and GENOTYPE FREQUENCIES OF THE ORIGNAL SAMPLE.
