I am astoundingly surprised you fell for that

An answer you will be sure to cheat off of? Nah. The explanation is simple. In fact, the answer IS in the link I gave you, you were too lazy to look through it.

Probability:

Number of Yellow Faces

___________________

Total Number of Faces

4N2

A number is divisible by 9 if the sum of the digits is a MULTIPLE of 9.

Solve for N (shouldn't be that hard it's basic adding and dividing)

3 red

2 blue

5 yellow

the probability of drawing either red or blue is

(red marbles + blue marbles)

A number is divisible by 6 if it is divisible 3 AND 2.

By divisibility of 3 rule:

2 + 1 + 4 + 2 + 0 + N = 9 + N

Let us try

N = 3 (nope because it is odd so it can't be divisible by 2)

N = 6 (yes!)

N = 9 (nope)

1 - 0.2 - 0.5 = What did you struggle on in this problem?

AltShaka,

I have looked on his account. He hasn't given free answers, although the answers were boxed and bolded. It depends on the QUESTION ASKER if the answer is "free or not".

If a question asker just looks at the answer and types it in and moves on, then the answer is free. If a question asker learns from the explanation, then the answer was not free.

I am friends with CalculatorUser in real life. I saw your previous posts asking CU and CPhill directly to help, by the looks of it, you seem to be pushing them to answer your question. Would they be giving free answers? They always include at least some explanation and work.

Please take DragonLord's response seriously and improve the quality of your questions next time! You still forgot to include numbers in your question!

Just to clarify

 - Is this supposed to be Combination/Permutation?

 - Or is this something more advanced?

$\frac{5*4*3*2*1}{(3*2*1)(2*1)}$

Can you evaluate this now?
