The output of a chemical process is continually monitored to ensure that the concentrationremains within acceptable limits. Whenever the concentration drifts outside the limits, the process is shut down and recalibrated. Let X be the number of times in a given weekthat the process is recalibrated. The following table presents values of the cumulativedistribution function F(x) of X. F(x) =0 if x<00.17 if 0≤x<10.53 if 1≤x<20.84 if 2≤x<30.97 if 3≤x<41 if x≥4(i) Graph the cumulative distribution function.(ii) What is the probability that the process is recalibrated fewer than 2 times during aweek?(iii) What is the probability mass function (PMF) for X
