In a classroom there are 23 girls and 25 boys. The class is to elect a President, Vice President, and a Treasurer. What is the probability if students were elected at random that all three positions were filled by girls? \frac{^{23}C_3}{^{48}C_3} \frac{^{23}P_3}{^{48}P_3} \frac{^{25}C_3}{^{48}C_3} \frac{^{25}P_3}{^{48}P_3}

There are 12 boys and 9 girls in a class. The teacher chooses two students at random. 3.1.1 Construct a probability tree diagram of the problem. 3.1.2 What is the probability that the teacher picks a boy and a girl? 3.1.3 What is the probability that the teacher chooses two students of the same sex? 3.2 Among Namibian registered voters, 30% are RDP, 50% are Swapo, and 20% are others. The percentages that support the president among these groups are respectively 0.10, 0.80, and 0.20. 3.2.1 If a person is picked at random, what is the probability that he/she supports the president? 3.2.2 If one is Swapo, what is the chance that he/she supports the president?
