5. in a bag of 30 cookies, there are 12 chocolate chip, 4 double chocolate chip, 5 peanut butter, 3 sugar, and 6 mint chocolate cookies. if sarah reaches in and takes a 2 cookies and eats them, what is the probability of her picking a chocolate chip cookie and then a peanut butter cookie? are these events independent or dependent?
2/29
60/ 870
3/6
12/16

 The correct option is

(A)

Step-by-step explanation:  Given that in a bag of 30 cookies, there are 12 chocolate chip, 4 double chocolate chip, 5 peanut butter, 3 sugar, and 6 mint chocolate cookies.

Sarah reaches in and takes a 2 cookies and eats them.

We are to find the probability that she picked a chocolate chip cookie and then a peanut butter cookie. Also, to check whether these events are independent or dependent.

Let A denotes the event that Sarah picks a chocolate chip cookie and B denotes the event that Sarah picks a peanut butter cookie.

So, the probabilities of events A and B are

Since the number of total cookies is reduced by one after Sarah picked and ate chocolate chip cookie, so

event B is dependent on event A.

Therefore, the events are dependent and the probability that Sarah picked a chocolate chip cookie and then a peanut butter cookie is

Thus, the required probability is and the events are dependent.

Option (A) is CORRECT.

it happens during combustion and impacts the environment because the plants and trees take in that and it can cause them to die.

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
