24The duration Y of long-distance telephone calls (in minutes) monitored by a station is a random variable with the properties thatP(Y= 3) = 0.3 and P(Y= 6) = 0.2.Otherwise, Y has a continuous density function given by= { 190,f(y) =ye-y/3y > 0,elsewhere.The discrete points at 3 and 6 are due to the fact that the length of the call is announced to the caller in three-minute intervals and the caller must pay forthree minutes even if he talks less than three minutes. Find the expected duration of a randomly selected long-distance call in minutes.min

P(Y=3) = 0.3 P(Y=6) = 0.2 For function : P = 1 - (0.3 + 0.2) = 0.5 Otherwise, Y has continues…

There are two Gaussian curves below (Plots A and B), along with the respective R source codes.Looking at the plots and the source codes provided, identify the parameters of respective Gaussian pdf's (probability density functions) and the numeric value of x in the PDF F(x)express the areas under the curves in terms of F(x). ( Do not calculate those areas.Your answers must be like F(x) or 1- F(x) for a relevant value of x.) Below is the source code and image for part B
