Suppose a college professor never finishes her lecture before the end of the class
period, and always finishes within five minutes after the class period is supposed to end. Let
X = time that elapses between the end of the class period and the actual end of the lecture.
Suppose the pdf of X is: (image)



Find the value of k that makes f(x) a legitimate probability density function, and use that
value of k to find the probability that the lecture ends less than 3 minutes after the class
period is supposed to end. 

 

f(x) = kx³/² 0 ≤ x ≤ 5 and 0 otherwise.
Transcribed Image Text:f(x) = kx³/² 0 ≤ x ≤ 5 and 0 otherwise.
