f(x) = \begin{cases} \frac{x}{25} & 0 < x < 5\\ \frac{10 - x}{25} & 5 < x < 10 \end{cases} The density function of a random variable X is given above. Find P(2.5 < X < 7.5).

Step 1
From the inequality x > 25, we know that x must be greater than 25. From the inequality 0 < x < S, we know that x must be between 0 and S. From the inequality 25 < S, we know that S must be greater than 25. So, the range of x that satisfies the given conditions Show more…
