Answer 5

Bot please help

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

Answer 6

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

Answer 7

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.

Answer 8

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.
