Solution: Independent events: Events are said to be independent, when the outcome of one event does not effect the outcome of other event.
Therefore from the given sets of events, the independent events are:
Flipping a coin and getting tails, then flipping it again and getting tails again.
Because the first flip will have no effect on second flip
Rolling a die a first time, then rolling the die a second time to get a sum of 9 .
Because the rolling of a die at first time have no effect on second rolling of die
Drawing a card from a deck, and drawing another card after returning the first one
to the deck.
Because drawing a card from a deck and then replacing back will have no impact on second draw.
flipping a coin and getting tails, then picking a card that is a diamond
Because flipping a coin and picking a card have no impact on each other
