Answer:

C) 0.38

Explanation:

Given the below;

p(owning a bike) = 0.33

p(owning a car) = 0.16

p(owning both) = 0.11

We'll use the below formula to determine the probability of owning a bike or a car;

[tex]\begin{gathered} p(\text{ owning a bike or a car) = }p(\text{ owning a bike) + p(owning a car) - p(owning both)} \\ \end{gathered}[/tex]

Substituting the given values, we'll have;

[tex]\begin{gathered} p(\text{ owning a bike or a car) = }0.33+0.16-0.11 \\ =0.38 \end{gathered}[/tex]
