Use R studio and show script

Soil or water pH is measured on a scale of 0-14. A pH reading below 7 is considered acidic, while a pH reading above 7 is basic. The pH level of water provided by a type of spray tank irrigator is equally likely to be either 6.8, 6.9, 7.0, 7.1 or 7.2. The water pH level is measured over the next two irrigations.

(a) Let X = be the average of the two pH measurements. Find the pmf of X and plot it in a histogram. (Hint: Use the command barplot(mypmfname) once you have the pmf)

(b) Let Y = be the number of acidic pH measurements in the two irrigations (so Y can be 0, 1 or 2). Find the pmf of Y and plot it in a histogram. (Hint: Use the command barplot(mypmfname) once you have the pmf)
