Heya !!

here is your answer !!!

number of red balls => 3


number of Black balls => 6


hence , total number of outcome => 9


first , probably of. getting red balls =>


number of possible outcome / total number of outcome

=>. 3 /. 9 => 1 / 3


now , total number of Black balls =>

number of possible outcome / total number of outcome


=> 6 / 9 => 2 /3


hence ,

1 / 3 and 2 /3


is your answer !!


hope it helps you dear !!!
