Which of the following experiments have equally likely outcomes? Explain
(i) A driver attempts to start a car. The car starts or does not start.
(ii) A player attempts to shoot a basketball. She/he shoots or misses the shot.
(iii) A trial is made to answer a true-false question. The answer is right or wrong.
(iv) A baby is born. It is a boy or a girl.

Solution:

(i) It is not an equally likely outcome because the probability of it depends on many factors.

(ii) It is not an equally likely outcome because the probability depends on the ability of the player.

(iii) It is an equally likely outcome because the probability is equal in both cases, it can be either true or false.

(iv) It is an equally likely outcome because the probability is equal in both cases, it can either be a boy or a girl.
