Assignment:
Q1. Terminology and symbols. Please interpret the symbol P(B ¦ A) and explain what is meant by the expression. Why is P(B ¦ A) not the same as P(B) ?
Q2. Consider the formulas: nPr = n! / (n - r)! and nCr = n! / (n - r)!r!
a. Given the same values for n and r in each formula, which is the smaller value, P or C? n = 10 and r = 2.
nPr = n! / (n - r)! = 10! / (10 – 2)! = 90
nCr = n! / (n - r)!r! = 10! / (10 – 2)!2! = 45
Value C is smaller.
How does this relate to the concept of counting the number of outcomes based on whether or not order is a criterion?
Provide complete and step by step solution for the question and show calculations and use formulas.
