Explanation:

Step1: Calculate total number of books

$110 + 165=275$

Step2: Calculate number of children's non - fiction books

50

Step3: Calculate probability of a children's non - fiction book

$P(\text{children's non - fiction})=\frac{50}{275}\approx0.182$

Step4: Calculate probability of not a children's non - fiction book

$P(\text{not a children's non - fiction}) = 1 - P(\text{children's non - fiction})=1 - 0.182 = 0.868$
