Question

The cumulative distribution function of a random variable X is (see attached photo):

a) What is P(X = 0)?

b) What is P(X > 1)? 

The image presents a piecewise function \( F(x) \) defined as follows:

\[
F(x) = 
\begin{cases} 
0, & \text{when } x < 0 \\ 
\frac{1}{2}, & \text{when } 0 \leq x < 1 \\ 
1, & \text{when } x \geq 1 
\end{cases}
\]

This means:
- \( F(x) = 0 \) for any value of \( x \) that is less than 0.
- \( F(x) = \frac{1}{2} \) for values of \( x \) that are greater than or equal to 0 but less than 1.
- \( F(x) = 1 \) for values of \( x \) that are greater than or equal to 1.
