Experiments (ii), (iii) and (v) have equally likely outcomes due to symmetry and equal chance. Experiments (i) and (iv) are not equally likely because mechanical conditions bias car starting and blue marbles outnumber red ones.
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) Tossing a fair coin once. (iii) Rolling a fair 6-sided die. (iv) Choosing a marble randomly from a bag that contains 3 red marbles and 7 blue marbles. (v) A baby is born. It is a boy or a girl.
