The continuous random variable X has the beta distribution with parameters and 3 if its density function is given by where > 0

The continuous random variable X has the beta distribution with parameters α and 3 if its density function is given by where α > 0 and β > 0. If the proportion of a brand of television set requiring service during the first year of operation is a random variable having a beta distribution with α = 3 and β = 2, what is the probability that at least 80% of the new models sold this year of this brand will require service during their first year of operation?
