Julo is drawing tiles from a bag of tiles like the one shown below. He draws a tile and replaces it, and draws another tile. what is the probability he will draw a red tile on both draws? @skate-4-life270

I thought it was going to end up being 5/15...or 1/3

OpenStudy (anonymous):

ok let me look

OpenStudy (anonymous):

ok so. how many of each does he have?

OpenStudy (anonymous):

he has 5 red, 3 yellow, 4 blue, and 3 green

OpenStudy (anonymous):

so first add them up

OpenStudy (anonymous):

which is 15

OpenStudy (anonymous):

ok so you will get 5/15, but he asks for if he does it twice so id say half of 5

OpenStudy (anonymous):

if not than you could do 5/30

OpenStudy (anonymous):

that would probably be better

OpenStudy (anonymous):

half of 5 is 2.5

OpenStudy (anonymous):

my choices are 2/25, 16/225,2/21,1/9

OpenStudy (anonymous):

hm ok let me think for a sec its been like 6 years sense ive done this

OpenStudy (anonymous):

haha ok

OpenStudy (anonymous):

im sorry i forgot to do this one would be 2/25

OpenStudy (anonymous):

OpenStudy (anonymous):

OpenStudy (anonymous):
