Suppose one of these 311 individuals is to be selected at random.
a. Find the following probabilities:
i. P 1male2
ii. P 1hybrid 2
iii. P 1hybrid 0 male2
iv. P 1hybrid 0 female2
v. P 1 female 0 hybrid 2
b. For each of the probabilities calculated in Part (a), write a sentence interpreting the probability.
c. Are the probabilities P 1hybrid 0 male2 and P 1male 0 hybrid 2 equal? If not, write a sentence or two explaining the difference between these two probabilities.
