(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:

A random experiment means the outcomes are unpredictable or have chances of different outcomes

So, while tossing a coin, we know that either head or tail appears . It is predictable

So, while rolling the die, we know either of the 6 numbers appears. It is predictable

Choosing a card from 52 cards, we can guess any of the cards can appear. It is predictable Therefore, throwing a stone from roof has no other outcome but to fall down

So, it is not a random experiment
