Which of the following are independent events. select all that apply
A flipping a coin and rolling a number cube
B choosing two marbles without replacement
C spinning a spinner twice
D choosing a car replacing it and then choosing another card
A. flipping a coin and rolling a number cube are independent events since the outcome of one event does not affect the outcome of the other event.
B. choosing two marbles without replacement are dependent events since the outcome of the first event affects the outcome of the second event.
C. spinning a spinner twice are independent events since the outcome of one spin does not affect the outcome of the other spin.
D. choosing a car replacing it and then choosing another card are independent events since the replacement of the first car means that the probability is the same for all cars on the second pick, regardless of what was chosen first.
Therefore, the independent events are A, C, and D.
A bag holds 3 blue marbles 5 red marbles and 2 green marbles find the probability of choosing a red marble and then a green marble with replacement
A 1/10
B 1/2
C 1/9
D 1/5
First, the probability of choosing a red marble on the first draw is 5/10 or 1/2 since there are 5 red marbles out of a total of 10 marbles in the bag.
Next, since the first marble is replaced, the probability of choosing a green marble on the second draw is also 2/10 or 1/5.
To find the probability of both events happening, we multiply the probabilities together:
1/2 * 1/5 = 1/10
So the probability of choosing a red marble and then a green marble with replacement is 1/10, or choice A.
1. To determine which of the options is an example of a dependent event, we need to understand what a dependent event is. In probability, an event is considered dependent if the outcome of one event affects the outcome of another event.
Option 4, "choosing a cookie at random, eating it, and then choosing another at random," is an example of a dependent event. The reason is that after eating the first cookie, the probability of choosing a certain type of cookie for the second selection changes. The outcome of the first event (eating a cookie) influences the probabilities for the second event (choosing another cookie).
2. To determine which of the options is an example of an independent event, we need to understand what an independent event is. In probability, an event is considered independent if the outcome of one event does not affect the outcome of another event.
Option 1, "choosing one sock at random from your drawer, putting it on, and then choosing another at random" is an example of an independent event. The reason is that the act of putting on one sock does not affect the probabilities of choosing a certain type of sock for the second selection. The outcome of the first event (choosing and putting on a sock) does not influence the probabilities for the second event (choosing another sock).
