Which of the following is an example of a dependent event?
1 flipping two coins
2 rolling a number cube and spinning a spinner
3 choosing two scoops of ice cream
4 choosing a cookie at random, eating it, and then choosing another at random
Although I think they want 4, it could be either 3 or 4.
If there are multiple ice cream containers, then it would be independent. If it was from the same container, then it would be dependent. Like the eaten cookie, the scoop is not replaced.
A dependent event is an event where the outcome of one event affects the outcome of another event. To determine which of the options is an example of a dependent event, we need to consider if the outcome of one event influences the outcome of the other event.
1. Flipping two coins: This is an example of an independent event because the outcome of the first coin flip does not affect the outcome of the second coin flip.
2. Rolling a number cube and spinning a spinner: This can be an example of either a dependent or independent event, depending on the specific situation. If the number rolled on the cube does not impact the probabilities or outcomes of the spinner, then it is an independent event. However, if the number rolled on the cube affects the sectors or probabilities on the spinner, then it becomes a dependent event.
3. Choosing two scoops of ice cream: This can be an example of both a dependent event and an independent event. If the selection of the first scoop does not influence the options or availability of the second scoop, then it is an independent event. However, if the selection of the first scoop affects the choices or availability of the second scoop, then it is a dependent event.
4. Choosing a cookie at random, eating it, and then choosing another at random: This is a prime example of a dependent event because the outcome of the first choice affects the options available for the second choice. After consuming the first cookie, it is no longer a possible choice for the second selection.
Therefore, option 4 - choosing a cookie at random, eating it, and then choosing another at random - is an example of a dependent event.
