A bag contains 36 marbles. If the probability of reaching in and pulling out a blue marble is 49, how many blue marbles are in the bag? Show your work or Explain.

Answer 1

49 is not a possible probability, as they are all less than 1.
I suspect you have garbled the fraction.

Answer 2

I suspect Ava meant that the prob is 4/9

4/9 = 16/36 , (I wanted 36 in the denominator since there were 36 marbles)

so there were 16 blue marbles

Answer 3

Sorry I didn't notice, I meant 4/9.
