Question

Thank you guys

Answer 1

Anyone?

Answer 2

You have 5+2+3+4+2 = 16 marbles. How many of them are not yellow? That number/total number of marbles is the answer.

Answer 3

2

Answer 4

You can think of this batch of marbles as:

2 yellow and (5 + 3 + 4 + 2 = 14) "non-yellow"

There are a total of 2 + 14 = 16 marbles.

The probability of a "non-yellow" draw is:

(# of non-yellows)/(# of totals marbles)

These # are given earlier in thi reply.

Answer 5

the choices are 8/9 or 9/16, 7/8, 3/4

Answer 6

That's good, because the correct choice is indeed among them. Just follow what I helped you with and you'll have no problem.

Answer 7

I did that earlier added all the numbers then divided by 5 ?

Good.

There are a total of 2 + 14 = 16 marbles.

Answer 19

right @whpalmer4 and @tcarroll010

Answer 20

so I simplify?

Answer 21

out of my choices it looks like I need too

Answer 22

And of course, once you simplify 14/16, you get . . . . what?

Answer 23

If you don't see 14/16 among the answer choices, reducing the fraction would be a good thing to try...

Answer 24

Hint: divide numerator and denominator by 2
