Answers
Answer:1 the car starting or not starting depends on how old the car is and does it have any other problem such as it had met an accident etc.
so, the factors if the car will start or not is not same in both cases
Therefore, it is not an equally likely outcome.
(i) it depends on how many shots he has taken and how good he is at shooting the ball.
so therefore, it is not an equally likely outcome.
(ii) the answer can only be right or wrong because it is a true or false question.
therefore it is an equally likely outcome.
(iv) it can be a boy or girl
therefore, it is an equally likely outcome
3. This is because when we toss a coin, it has only two outcomes either head or tail. A coin is always unbiased. So, tossing a coin considered to be a fair way of deciding which team should get the ball at the beginning of a football game
