Question

which is a pair of dependent events? spinning a spinner one time and then spinning it a second time flipping a quarter and then flipping a nickel removing a marble from a bag, not putting it back, and then removing a second marble rolling a number cube and then choosing one letter from the alphabet

Answer 1

Answer and explanation:

Two events are said to be dependent on each other, if the outcome of the first thing affects the outcome of the second thing in such a way that the probability changes.

Here, the right answer will be = removing a marble from a bag, not putting it back, and then removing a second marble.

Explanation:

Lets suppose there were 10 marbles in the bag at the first place. Now, you removed one marble and did not put it back. So, remaining marbles will be 9. Now, if again you choose a marble, you have 9 marbles to choose from. We can see that probability changes with the event that occurred at first place.

So, this is the right answer.

Rest options are simultaneous one. They are not dependent in any way.

Answer 2

Removing a marble and not putting it back. Doing so changes the probability and throws the whole thing off. Flipping a coin, be it a quarter or nickel, will always be 50/50. But the marbles depend on whether you put them back in the bag or not.
