Question 5
Which of the following is not a random experiment?
(a) Tossing a coin
(b) Rolling a dice
(c) Choosing a card from a deck of 52 cards
(d) Thowing a stone from a roof of a building
Ans: (d)
Tossing a coin, rolling a die and choosing a card from a deck of 52 cards are the random experiments, as in these cases the outcome cannot be predicted with certainty. But if we throw a stone from the roof of a building, we know the output, it will fall on the ground(certain/fixed outcome).
