both Aand B is answer

Answer 2

Answer:

i) 1/4 ii) 1/3 iii and iv) 28/48

Step-by-step explanation:

Total no of balls= 12+16+20=48

i) P(white ball) = 12/48 => 1/4

ii)  P(Red ball) = 16/48 => 1/3

iii)  P( red or white ball) = 28/48

iv) P(not a green ball) =  28/48

As the 4th one says that not a green ball so we need to take other two types of balls
