Answer:
i think your answer would number 1 or number 4
Step-by-step explanation:
There are 22 roses in the vase
probability of first selecting a red rose = 8/22 = 4/11
P( second one is red) = 7/21 = 1/3
these probabilities are multiplied because the individual picks are independent
so the answer is 4/11 * 1/4 = 4/33
36÷4. 4 goes into 36, 9 times. Do your check work, which would be 9x4=36√. Hope that helps!
Answer:

Step-by-step explanation:
Since the height isn't given, we assume it to be "h" (of cylinders). And the answer will be in terms of "r" and "h".
The area of 1 arm is given, so the area of 2 arms would be:

Now, area of 2 cylinders would be the formula:

So, total area is A_arm PLUS A_cyl. The fractional area the arms are would be gotten by taking expression A_arm divided by A_total.
Shown below:

We simplify further:

THis is the answer.
