(c) Find the probability that at least one of the five has type B+ blood.

(d) Which of the events can be considered unusual? Explain.

Review the Hardy-Weinberg equilibrium equation. What parts of the equation represent gene frequencies? What elements represent genotype frequencies and phenotype frequencies? Are genotype and phenotype frequencies always the same? Use a hypothetical population to specify alleles and allelic frequencies as you develop your presentation.
