QUESTION FIVEAt Zambia ICT college, 79% of the of student population were born in Ndola, 20% inthe rest of the on the Copperbelt (Except Ndola) and the remaining 1% in Zambia(Except the copperbelt). Two people are selected at random.a. Using your graph paper, represent the above information on a tree diagramb. Find the probability that at least one of these people was born in Ndola.c. Find the probability that both of these people were born on the rest of the copperbeltgiven that neither was born in the rest of Zambia.d. Using Boolean laws, show that [(A U B) – (An B)]' = Ø%3DThe equation x2 + 2px + (3p + 4) = 0, where p is a positive constant, has equal rootse. Find the value of pf. For this value of p, solve the equation x2 + 2px + (3p + 4) = 0

People often match their behavior to their social environment. One study of this idea first established that the type of music most preferred by black college students is R&B and that white college students' most preferred music is rock. Will students hosting a small group of other students choose music that matches the makeup of the people attending? Assign 9090 black business students at random to three equal‑sized groups. Do the same for 9696 white students. Each student sees a picture of the people he or she will host. Group 1 sees six blacks, Group 2 sees three whites and three blacks, and Group 3 sees six whites. Ask how likely the host is to play the type of music preferred by the other race. Use ANOVA to compare the three groups to see whether the racial mix of the gathering affects the choice of music.
