Natural red hair consists of two genes. People with red hair have two dominant genes, two regressive genes, or one dominant and one regressive gene. A group of 1000 people was categorized as follows:

Let A denote the event that a person has a dominant red hair gene, and let B denote the event that a person has a regressive red hair gene. If a person is selected at random from this group, compute the following:

(a) P(A)

(b) P(A ˆ© B)

(c) P(Aˆª B)

(d) P(A ˆ© B)

(e) P(A | B)

(f) Probability that the selected person has red hair
