Answer:
Yes, snow and cold weather are independent.
Step-by-step explanation:
We are given the following in the question:
C: Cold weather
S: Snow
P(C) = 0.50
P(S) =0.30
![P(S\cap C) = 0.15](https://tex.z-dn.net/?f=P%28S%5Ccap%20C%29%20%3D%200.15)
We have to check whether snow and cold whether are independent events.
If the events A and B are independent then,
![p(A\cap B) = P(A)\times P(B)](https://tex.z-dn.net/?f=p%28A%5Ccap%20B%29%20%3D%20P%28A%29%5Ctimes%20P%28B%29)
Checking,
![p(S\cap C) = P(S)\times P(C)\\0.15 = 0.30\times 0.50](https://tex.z-dn.net/?f=p%28S%5Ccap%20C%29%20%3D%20P%28S%29%5Ctimes%20P%28C%29%5C%5C0.15%20%3D%200.30%5Ctimes%200.50)
Thus, the two events are independent.
For mutually exclusive events
![P(A\cap B) = 0](https://tex.z-dn.net/?f=P%28A%5Ccap%20B%29%20%3D%200)
Thus, the given events are not mutually exclusive.
Answer:
Answer: Kayla used 2&5/24 cups of paint all together.
Step-by-step explanation:
Kayla paints a bookcase by using
1 5/6 cups of paint on the outside of the bookcase. Converting 1 5/6 cups to improper fraction, it becomes 11/6 cups of paint.
She also used 3/8 cup of paint on the inside.
Therefore, the total number of cups of paint that Kayla used all together would be cups of paint:
Converting to mixed fraction, it becomes
<u>2 and 5/24 cups of paint</u>
