What is the frequency of the recessive allele

A population of 100 crickets contains 65 individuals that can produce long, extended noises. The ability to produce such sounds is governed by a single gene with only two alleles; one is completely dominant to the other. Thirty of these 65 crickets are heterozygous. Use this information to answer the question below.

You return to this population after 5 years. Assume that it has reached a point of Hardy-Weinberg equilibrium (and none of the assumptions of this theorem are violated). What proportion of the population is expected to have at least one recessive allele?

What is the frequency of the recessive allele?
