23. 1995 Mathematics Paper A Q13a Next Page Answer key Sam has 3 different spinners. He chooses ONE of his spinners. He spins it 100 times and writes down how it lands each time. The results of the 100 spins are numbers only from 1 to 3. Which spinner do you think he is using? Give ONE reason why you chose this one. Spinner?
24. 1995 Mathematics Paper A Q13 (a) Both A and B have the numbers 1 to 3. The reason given for choosing A or B should make reference to this, eg: · “Because A has only the numbers 1 to 3 on it.” · “Only the numbers 1, 2 or 3 might turn up on B.” · “Because A has the most 3s, 2s and 1s.” 1 No mark is awarded for choice of spinner. Do not award marks for reasons which are vague or inappropriate, eg: · “Because it’s got the right numbers.” A reason is inappropriate if it refers to non-mathematical criteria or irrelevant mathematical criteria, eg: · “Because it’s his favourite.” Next Page
25. 1995 Mathematics Paper A Q13b Next Page Answer key 1. Sam has 3 different spinners. Sam spins A 100 times and B 100 times. The arrows on the line show how many times each spinner lands on an odd number. He spins C 100 times. Put an arrow on the line to show your estimate of how many times spinner C will land on an odd number . Explain why you put the arrow there.
26. 1995 Mathematics Paper A Q13 Next Page (b) The arrow should be within the shaded range of 25 to 40, inclusive. (c) Explanation which refers to the fact that 1/3 or 2/6 of the numbers on C are odd OR which makes a comparison with the number of odd numbers on A or B, eg: 1 · “There are less odds on C.” · “Because it has only two odd numbers on.” The answer for (c) should be considered independently of the answer for (b). Accept (c) may be correct even if (b) is wrong.
