In a population of beetles, two alleles determine body colour: allele A (green) and allele a (brown). Before selection the population is in Hardy\u2013Weinberg equilibrium. After a selective event, 64\% of the surviving beetles are green and 36\% are brown. The selection acts only on the brown phenotype, reducing its survival to 75\% of the unselected brown beetles. Determine the original frequency of allele A (p) before selection. Give your answer to two decimal places.
