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.

$I$ toss three coins together. The possible outcomes are no heads,$1$ head,$2$ heads and $3$ heads. So,$I$ say that probability of no heads is $\frac{1}{4}$. What is wrong with this conclusion?
