OpenStudy (anonymous):

there are 18 yellow and 2 white balls in the bag

OpenStudy (anonymous):

OpenStudy (anonymous):

lol answer me

OpenStudy (anonymous):

huh ?? u didnt ask a question

OpenStudy (anonymous):

think about the first draw only, you have 20 balls in the bag, and 18 of them are yellow, what is the change that u pick a yellow ball on your first try

OpenStudy (anonymous):

ummmmmmmmmm 18/20 idk bro

OpenStudy (anonymous):

@dan915 yo thx 4 da mdeal

OpenStudy (anonymous):

yep that is right immabe!

OpenStudy (anonymous):

then he puts the ball back and once again you are left with the same situation for hte 2nd pick

OpenStudy (anonymous):

so theres another 18/20 chance to pick up the yellow ball again

OpenStudy (anonymous):

so its like 18/20 chance in an 18/20 chance you can multiply these 2 fractions together to see the total chance

OpenStudy (anonymous):

(18/20) * (18/20) =(18/20)^2

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

i can help you understand why multiplying is working if its not clear

OpenStudy (anonymous):

@Peaches15 that medal was actually a misclick lol xD but u can keep it

OpenStudy (anonymous):

@dan915 duh of cures im keeping da medal lol

OpenStudy (anonymous):

Ok i multiplied 18*20 got 360 then i divided that by 2 an got 180 wrong or right

OpenStudy (anonymous):

OpenStudy (anonymous):
