This study aims at presenting the educational model for the effective application of probability and statistics to the H/W curriculum. In order to do this, this paper conducts a survey with H/W major college students, and then analyzes how probability and statistics can be correlated with other H/W core subjects and how the knowledge of probability and statistics can affect the understanding of H/W majors through the actual class experiment. Consequently this study suggests probability and statistics as a prerequisite subject in the H/W curriculum.
