Question

Which of the following are independent events? Select all that apply

1.You flip a coin and roll a number cube.
2.You draw a marble from a bag, replace it, and draw again.
3.You randomly choose 2 socks from a drawer, hoping they will match.
4.You draw two numbers from 1 to 10 from a hat without replacing the first.

Answer 1

i know it is the coin but that is true about the draw a marble from the bag and put it back and draw another cuz it will be the same but i kinda thought it was you draw 2 numbers cuz it doesnt affect anything either unless if it was for something else

Answer 2

Independent events are events which do not affect each other in any way. Therefore the independent events from this list are as follows:
1, 2.
If you flip and coin, it isn't going to affect the outcome of the dice. Similarly, if you draw a marble form a bag and REPLACE it, you will still have the same number of marbles in the 2nd draw, meaning that the first draw wouldn't affect it.
