In how many different ways can a committee of 4 students be chosen from 6 students?
Ans: 6C4 = 6C2 = (6*5)/(1*2) = 15
============================================

What is the simple interest rate if p = $4,000, t = 2 years, and I = $320?
Use I=prt, where t is in years.

r = 320/8000
---
r = 0,04 = 4%
