Explanation Approach: This concept is related to sets and subsets. Set H is a subset of W if every element of set H is also an element of the set W . For example, if A = 2 , 4 , 6 , 12 and G = 2 , 4 , 6 , 8 , 12 , 14 then A is a subset of G . This can be written as A ⊆ G . In the above example, there are some elements in G that are not in A , so G is not a subset of A and can be written as G ⊈ A . As we see in Figure 1.1; W indicates people who are working to reduce global warming and H indicates people who are striving to reduce world hunger. r 1 is not a subset of W nor H . Thus, can be written as r 1 ⊈ W and r 1 ⊈ H r 2 is a subset of W but not H . This can be written as r 2 ⊆ W and r 2 ⊈ H r 3 is subset of W & H ; i

(b) An otherwise fair six-sided die has been tampered with in an attempt to cheat at a dice game. The effect is that the 1 and 6 faces have a different probability of occurring than the 2, 3, 4 and 5 faces. Let θ be the probability of obtaining a 1 on this biased die. Then the outcomes of rolling the biased die have the following probability mass function. Table 1 The p.m.f. of outcomes of rolls of a biased die Outcome 1 2 3 4 5 6 Probability θ 1 4 (1 − 2θ) 1 4 (1 − 2θ) 1 4 (1 − 2θ) 1 4 (1 − 2θ) θ (i) By consideration of the p.m.f. in Table 1, explain why it is necessary for θ to be such that 0 < θ < 1/2. [2] (ii) The value of θ is unknown. Data from which to estimate the value of θ were obtained by rolling the biased die 1000 times. The result of this experiment is shown in Table 2.
