we are required to find the probability to randomly select from the union of those who own a smartphone only and those who own a smartphone and computer.
an addition of the subsets cover the entire set.
6 + 15 + 26 + 32 + 21 = 100%
let
p(A)= probability of smartphone only
p(B) = probability of smartphone and computer
p(A U B) = P(A) + P(B)
= 15% + 32%
= 47%

Given,
2 cups of yellow paint is needed for every 3 cups of red paint to make a batch of orange paint,
So, the ratio of yellow paint and red paint in a batch of orange paint = 2 : 3
