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****?
nvm i know
The correct answer is option 4, "choosing a cookie at random, eating it, and then choosing another at random."
To determine if an event is dependent or independent, we need to understand if the outcome of one event affects the outcome of the other event.
In options 1, 2, and 3, the events are independent because the outcome of one event does not influence the outcome of the other event. Flipping two coins, rolling a number cube and spinning a spinner, or choosing two scoops of ice cream can all be considered as separate events, and the result of one does not affect the outcome of the other.
However, in option 4, the events are dependent. After choosing and eating the first cookie, the number of remaining cookies changes, influencing the outcome of choosing the second cookie. The probability of selecting a specific type of cookie on the second choice depends on what was chosen and eaten on the first choice.
Therefore, selecting a cookie at random, eating it, and then choosing another randomly is an example of a dependent event.
