In a certain webinar series, a speaker cannot finish his talk before the end of one hour and always finished his talk within two minutes after one hour. Let Xbe the time between the end of one hour and the end of the talk. The probability density function is defined by f(x) = kx2 for 0 sx s 2, O if otherwise. What is the probability that the talk continues beyond the %3D hour for between 60 and 90 sec?
