Circling of ‘No’ AND an explanation which implies that every spin offers equally likely outcomes, eg ‘It’s still 50 – 50 no matter how many heads you get’;‘Heads and tails are equally likely because it’s a fair coin’;‘The probability is equal’;‘It’s a fair coin’.Do not award a mark for circling ‘No’ alone.Do not award a mark for the question if: ‘Yes’ is circled;OR neither ‘Yes’ nor ‘No’ is circled; unless the explanation unequivocally implies ‘No’.Do not accept vague or arbitrary explanations such as: ·
‘You can’t tell’;‘Time for tails but heads could still come’;‘It could be either’;‘There are 2 sides to the coin’.
