Answer:
Step-by-step explanation:
Let X be the number of tickets issued by a meter reader for parking-meterviolations can be modeled by a Poisson process with a rateparameter of five per hour.
X is Poisson with parameter =5per hour
a) the probabilitythat exactly three tickets are given out during a particular hour
=
b) the probabilitythat at least three tickets are given out during a particularhour
=
c) tickets we expect to be given during a 45-min period
=

Answer:
a. 205320
b. 34220
c. 60! / (35)! (25)! + 60!/ (40)!(20)! + 60!/ (45)! (15)!
Step-by-step explanation:
a) The number of ways to dustribute exams among the TA's is:
n / (n - r)!
n= number of things to choose from
r= Choosing r number
60P3= 60! / (60 - 3)!
(60)(59)(58)(57)! / (57)!
=205320
B) The number of ways to dustribute the exams among the TA's is:
n! /(n - r)! r!
60C3= 60! /(60 - 3)! 3!
= 60!/ 57! 3!
= 60 × 59 × 58 / 3 × 2 × 1
= 34220
C) The required number of ways is:
60C25 + 60C20 + 60C15
= 60! / (35)! (25)! + 60!/ (40)!(20)! + 60!/ (45)! (15)!
Unfortunately, there's no diagram here! But the prism is described as "rectangular." Thus, the volume is simply (length)(width)(height) cubic inches. Multiply: (8 inches)(9 inches)(12 inches).
