### Probability and Statistics Problem Set

**Problem Q4:**

The probability density function (PDF) of the random variable (RV) \( X \) is given by:

\[ f(x) = 5e^{-kx} \text{ for } x \geq 0. \]

Tasks:

a) Determine the value of \( k \).

b) Calculate the probability that \( X > 1 \).

c) Given \( Y \sim N(2, 2) \) and \( X \) and \( Y \) are independent, find the probability:

\[ P(0.25 \leq X \leq 0.5 \text{ and } 0.1 \leq Y \leq 0). \]

**Notes:**

- Utilize integration to solve part (a) for \( k \) to ensure the total area under the PDF is equal to 1.
- For part (b), use the cumulative distribution function (CDF) or direct integration.
- To solve part (c), calculate the probabilities separately for independent events, using properties of the normal distribution for \( Y \).
