In everyday language people often mix up the ideas of events that must happen, may happen, or can never happen. Consider the statements below and answer the questions that follow:
a. (i) A weather bulletin says, “Tomorrow it will either rain or not rain in Delhi.” Identify whether the described event is sure, impossible or neither. Give a reason.
b. (ii) A friend claims, “I will roll a standard dice tomorrow and get a number larger than 10.” Classify this event with reason.
c. (iii) Explain clearly what is meant by ‘equally likely outcomes’ using the example of tossing a fair coin.
d. (iv) Distinguish between an impossible event and a sure event by writing two differences other than the value of their probabilities.
