Question

A bag contains 8 black marbles, 16 white marbles, 14 red marbles, and 10 green marbles. A marble is to be drawn from the bag without looking.


What is the probability that the marble drawn will not be white?

A. 1/3


B. 2/3


C. 3/4


D. 15/16

Answer 1

So we've got a couple of steps here...
~We need to know how many marbles there are in `total`.
~Then .. we can determine the probability that a red marble WILL be drawn, and subtract that from 1 to get the probability that a red marble will not be drawn.

If that second step is confusing, we can instead add up all of the marbles that are `not red` and divide by the total number of marbles, that will give us our probability that the marble drawn is not red.

Answer 2

How many marbles in total? :)

Answer 3

Oh it says white now? :3 did you change it or am i crazy? lol

Answer 4

I think the answer will be A 1/3 I'm correct?

Answer 5

Hmmmmm, I don't think that's correct :o

Non-White marbles: 8+14+10 = 32
Total marbles: 8+16+14+10 = 48

Probability of drawing a non-white marble: 32/48

Hmm I don't think that simplifies to 1/3!

Answer 6

ok make sense lol, thanks anyway

Answer 7

true, but can simplifies 32/48 and get 4/6 = 2/3 so the answer will be B 2/3
