Abag hold 1 blue block and 3 yellow block. how many green blocks should be added to the bag to makr the probability of randomly selecting a greem black from the bag equal to 1/2 ?

Hello,

Since there is 1 blue block and 3 yellow blocks that would equal to 4 blocks in total. So the question is asking how many green blocks would be needed to make it 1/2. So you would be needing 4 green blocks to make the probability of randomly selecting a green block from the bag to equal 1/2.

I hope this helped you!
