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.
Not equally likely. The outcome depends on the mechanical condition of the car. If the car is in good condition, it will start; otherwise, it will not. The probability is not 1/2.
Not equally likely. The outcome depends on the player's skill. A skilled player has a high probability of shooting, while an unskilled player has a high probability of missing.
Equally likely. There are only two possible outcomes (right or wrong), and the chance of guessing correctly is the same as guessing incorrectly (1/2).
Equally likely. The probability of a baby being a boy or a girl is approximately equal (1/2).
Explanation
The question tests the understanding of 'equally likely outcomes', which means all outcomes have the same probability of occurrence. (iii) and (iv) are equally likely because the chances are mathematically equal (1/2). (i) and (ii) are not equally likely because the outcomes depend on specific conditions (car's health, player's skill) rather than random chance.
