    Find the probability that none of the 5 bulbs in a signal light will have to be replaced during the first 1200 hours of operation if the lifetime X of the bulb is a random variable with the density
    f(x)=6[0.25-(x-1.5)^2] when 1<=x<=2, and
    f(x)=0 other wise

    Where x is measured in multiples of 1000
