Question Let \( \mathrm{X} \) be a set with exactly 5 elements and \( \mathrm{Y} \) be a set with exactly 7 elements. If a is the number of one-one functions from \( \mathrm{X} \) to \( \mathrm{Y} \) and \( \beta \) is the number of onto functions from \( \mathrm{Y} \) to \( \mathrm{X} \), then the value of \( (1 / 5 !)(\beta-\alpha) \) is📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
