Question

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


Solution

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).
