Explanation Given: A number 24 , 013 . Approach: Since 3 and 4 are factors of 12 . We will check if the number 24 , 013 is divisible by 3 and 4 . Calculation: 3 and 4 are factors of 12 . According to the division rule of 3 : A number is divisible by 3 if the sum of the digits of the number is divisible by 3 . 24 , 013 = 2 + 4 + 0 + 1 + 3 = 10 . Since 10 is not divisible by 3 . ∴ 24 , 013 is not divisible by 3 To determine b. Whether 24 , 036 divisible by 12 . To determine c. Whether 17 , 034 divisible by 17 . To determine d. Whether 2 ⋅ 3 ⋅ 15 ⋅ 21 divisible by 27 . To determine e. Whether 2 ⋅ 3 ⋅ 5 ⋅ 7 + 1 divisible by 6 .

(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.
