There is a large bag with marbles in it. There are 23 red ones, 16 black ones, 5 blue ones, 17 orange ones, 4 white ones, and 15 purple ones. Juanita reaches in without looking and selects one marble.

What is the probability that it is purple?

 What is the probability that it is purple?

Hint: 
Add 23 + 16 + 5 + 17 + 4 + 15 to find the total number of marbles.

anonymous · Answer

80

hero · Answer

Okay, so since 

$$\text{Probability} = \frac{\text{Part}}{\text{Whole}} =\frac{\text{total number of purple}}{\text{total Number of marbles}} $$

What do you believe is the fraction?

anonymous · Answer

1/15 @Hero

hero · Answer

So there's 1 purple marble and 15 total marbles in the bag?

anonymous · Answer

no 80 marbles @Hero

hero · Answer

And how many purple marbles are there?

anonymous · Answer

15

hero · Answer

Okay so the initial fraction should be $\frac{15}{80}$ no?

anonymous · Answer

nope

anonymous · Answer

@Hero noo

hero · Answer

Why not?

anonymous · Answer

@Hero because its not one of the answers

hero · Answer

That's because you haven't reduced it yet.

anonymous · Answer

ohhh  yeahh how do i do that @Hero

hero · Answer

Break down the numerator and denominator into prime factors, then cancel factors of 1.

anonymous · Answer

1/80 or 1/15? @Hero

hero · Answer

neither. Nice attempt at guessing though.

hero · Answer

You have no clue how to reduce fractions do you?

anonymous · Answer

not guessing those are just options from my stuff and no not really lol

hero · Answer

anonymous · Answer
