Suppose student Ana is running for a charity and asks her friend to chip in the donation. Suppose each friend donates independently, and the donated value T is a random variable with the following probability density: c ti € [5, 10] dollars p(T₁ = ti) = { t € [35, 40] dollars.

Let's assume It's are mutually independent and each donation is a continuous random
variable given they're using electronic transfer. Ana requested from 150 friends for the
donation. Let X be the total amount in dollar Ana collected from these 150 friends. You
need to simplify for this problem.
