A bag contains 4 white 2 blue 5 red marbles. 1. Find the probability of choosing a red marble than a white marble if the marbles are replaced. 1/12 5/36 5/6 5/12

OpenStudy (anonymous):

I think it's 5/12 but I'm not sure.

OpenStudy (anonymous):

Nope. Take the odds of a red marble and then a white marble, then multiply.

OpenStudy (anonymous):

What is the extra 1 after all the marbles

Are you sure that you have typed the question and the answer choices correctly?

OpenStudy (anonymous):

I'm sure.

OpenStudy (kropot72):

If it is all typed correctly, then none of the answer choices is correct.

OpenStudy (anonymous):

Perhaps 6 red marbles?

OpenStudy (anonymous):

Unless it's 3 blue marbles?

OpenStudy (anonymous):

since the marbles are replaced, we end up with a denominator of 121, which has no common factors with the given options. So its a mistake in your options
