Which of the following is an example of an independent event? (1 point)
choosing one sock at random from your drawer, putting it on, and then choosing another at random
flipping a coin and rolling a number cube
choosing students at random for basketball teams
removing a marble from a bag, and then choosing another without replacing the first

dependent in the first one would be choosing a cookie at random and eating it and then choosing another. By eating that first cookie, you changed the probability of getting a second cookie.
Indep for the second one would be flipping a coin and rolling a cube. 
O_O ^^

The outcome of choosing the first card has affected the outcome of choosing the second card, making these events dependent. Definition: Two events are dependent if the outcome or occurrence of the first affects the outcome or occurrence of the second so that the probability is changed.
