Let AAA be the event that a randomly selected student in the class has a sister and BBB be the event that the student has a brother. Based on this information, answer the following questions. What is P(A)P(A)P, left parenthesis, A, right parenthesis, the probability that the student has a sister? What is P(B)P(B)P, left parenthesis, B, right parenthesis, the probability that the student has a brother? What is P(A\text{ and }B)P(A and B)P, left parenthesis, A, start text, space, a, n, d, space, end text, B, right parenthesis, the probability that the student has a sister and a brother? What is P(B\text{ | }A)P(B | A)P, left parenthesis, B, start text, space, vertical bar, space, end text, A, right parenthesis, the conditional probability that the student has a brother given that he or she has a sister? Is P(B\text{ | }A)=P(B)P(B | A)=P(B)P, left parenthesis, B, start text, space, vertical bar, space, end text, A, right parenthesis, equals, P, left parenthesis, B, right parenthesis? Are the events AAA and BBB independent?
