Answer:
16.7%.
Step-by-step explanation:
There are initially 
pencils in the bag.
Take a pencil out of this bag of 47 pencils. 15 out of the 47 pencils blue. Let 
represent the event of getting a blue pencil on the first pick. The probability of getting a blue pencil is:
.
There are now 
pencils left in the bag. However, given that the first pencil removed from the bag is blue, the number of red pencils in the bag will still be 24. Take another pencil out of this bag of 46 pencils. Let 
represent the event of getting a red pencil on the second pick. The possibility that the second pencil is red given that the first pencil is blue will be:
.
The question is asking for the possibility that the first pencil is blue and the second pencil is red. That is:
.

This all depends on the content you are studying, and what learning style works for you. One thing that works for most people is repetition. Although it sucks, it works because that’s how our brains are wired. Tell yourself, “I will not stop studying until I understand this concept or calculation,” for example. Then take a break once you are comfortable with it. Repeat again as needed. Start studying early and only study what you don't know. Try to be as consistent as possible. Good luck!
You can divide 84 and 144 and convert the answer to a fraction.
Correct me if I am wrong.
So here just plug values into the quadratic formula x= -b+- sqr b^2-4ac / 2a
