This attempt took 65 minutes. Question 1 pts
You may find the following files helpful throughout the exam: Statistics_Equation_Sheet Links to an external site. Find the answer to each of the following by first reducing the fractions as much as possible:
a) P(490,2)= b) C(670,665)= Your Answer:
a)P (490,2)= n =490 r= 2 P = n!/(n-r)! = 490-2 =488
=490/488= P= 490x489=239610
P(490,2)= 239610 b)C(670,665)= C =n!/r!(n-r)!= n=670 r =665
=670!/665!(670-665)!=5 C(n,r)=670x669x668x667x666/5x4x3x2x1
C(670,665)=133007902876080/120= 1108399190634
a. b. Question 2 pts
You may find the following files helpful throughout the exam: Statistics_Equation_Sheet Links to an external site. Suppose you are going to make a password that consists of 6 characters chosen from {1,4,7,8,b,c,e,k,n,t,z}. How many different passwords can you make if you cannot use any
character more than once in each password?
Your Answer:
1478bcekntz= 11 letters= n=11
6 characters= n1=11,n2=10,n3=9, n4=8, n5=7, n6=6
P(11,6) =11x10x9x8x7x6= 332640
