A student is selected at random to assist in a demonstration. a) What is the probability that the student selected is a female junior P (FJ)? b) What is the probability that the student selected is a male given they are a senior P (MIS)? 3) If P(A)=0.4, P(B)=0.6, and P(A and B)=0.24, what conclusion can you make about A and B? Explain your reason. (1) P(A|B)=0.6 (2) A and B are independent events (3) A and B are not independent events (4) No conclusion is possible Regents Questions of Independence 1) Given events A and B, such that P(A) = 0.6, P(B) = 0.5, and P(A U B) = 0.8, determine whether A and B are independent or dependent. 2) The results of a poll of 200 students are shown in the table to the right. For this group of students, do these data suggest that gender and preferred music styles are independent of each other? Justify your answer.
