10. (Topic I.4) Suppose that a large set of quantitative data has median 43, first quartile Q1 = 35, and third quartile Q3 = 47. Suppose that the two largest data values in this set are 59 and 57, and that the two smallest data values are 15 and 22. Use this information to draw a boxplot for this data set horizontally above the axis below. Label the relevant values in your diagram.

0 5 10 15 20 25 30 35 40 45 50 55 60 65 70

11. (Topic I.5) Consider the experiment of tossing a coin three time and noting whether heads or tails comes up. Let A be the event that the first toss is heads and let B be the event that exactly one toss comes up tails. a) Calculate P (B). (Explain how you know your answer is correct.)

b) Calculate P (B |A), the conditional probability of B given A. (Explain your answer.)
