Question: An important factor in solid missile fuel is the particle size distribution. Significant problems occur if the particle sizes are too large. From production data

An important factor in solid missile fuel is the particle size distribution. Significant problems occur if the particle sizes are too large. From production data in the past, it has been determined that the particle size (in micrometers) distribution is characterized by f(x) = 3x−4, x> 1, 0, elsewhere.

(a) Verify that this is a valid density function.

(b) Evaluate F(x).

(c) What is the probability that a random particle from the manufactured fuel exceeds 4 micrometers?
