Expected frequency for a person having tongue rolling ability and attached earlobe?

The expected frequency would be determined by calculating the probability of someone having both traits based on their individual frequencies in the population. This would involve multiplying the frequency of tongue rolling ability by the frequency of attached earlobes in the population. For example, if 70% of the population can tongue roll and 60% have attached earlobes, the expected frequency would be 0.70 x 0.60 = 0.42, or 42%.
