It is observed that in a particular group of plants: 75% are tall and 25% are short; and 75% have a round seed shape and 25% have a wrinkled seed shape. Calculate the probability of finding each of the following four combinations (assume that the height and seed shape are not related):

(i) tall with a round seed

(ii) short with a round seed

(iii) tall with a wrinkled seed

(iv) short with a wrinkled seed
