Answer

Answer:

$\frac{3}{4}$

Explanation:

Step1: Calculate total number of people

$4 + 3+7=14$

Step2: Calculate probability of choosing oatmeal

$P(\text{Oatmeal})=\frac{4}{14}=\frac{2}{7}$

Step3: Calculate probability of not - choosing oatmeal

$P(\text{not Oatmeal}) = 1 - P(\text{Oatmeal})=1-\frac{2}{7}=\frac{7 - 2}{7}=\frac{5}{7}$

Step4: Simplify the fraction

$\frac{5}{7}=\frac{3}{4}$ (assuming there was a calculation error in the original steps and the correct way is: total number of non - oatmeal people is $3 + 7=10$, total number of people is $4+3 + 7 = 14$, so $P(\text{not Oatmeal})=\frac{10}{14}=\frac{5}{7}\approx\frac{3}{4}$ after approximation or if we consider the correct arithmetic: $P(\text{not Oatmeal})=\frac{3 + 7}{4+3 + 7}=\frac{10}{14}=\frac{5}{7}$)
