3. In a survey of statistics students, it is found that 54 use RStudio, 43 use SAS, and 32 use Stata, for data analysis. Moreover, 29 use both RStudio and SAS, 18 use both RStudio and Stata, and 21 use both SAS and Stata, for data analysis. Fifteen of these students use RStudio, SAS, and Stata, while nine of them use tools other than R Studio, SAS, and Stata. d. [1pt] How many students use RStudio only for data analysis? e. [1pt] How many students use at least two software for data analysis? f. [1pt] How many students use SAS or Stata, but not both?
