Question 14: Compute E[X] O 0.8 O 0.6 O 0.4 O 0.2 Question 15 1 pts Use the following information for Questions 15 - 16. A study determined that the number of drivers who travel between a particular origin and destination during a designated time period has a Poisson distribution with parameter p = 20. What is the probability that the number of drivers will: Questions 15: Be at most 10? 0.351 O 0.441 0.011 O 0.291

Answer 1

• 
  Given data P= 0.2 nza e(x)= nO = 8X OR= 0 option
  
  here poisson distribution with parameter & P(X=re) - ded ,20,1,2,3,4,---- , here da La here given data poisson distribution with parameter all=20 =) P(x=x)= e de x30,1,2,3, ~- 21 P (be at most 10) = P(X=10) = A PCatmost lo) = (205*270 = 0.0108 0:0|| Plbe almost 10) = 0.011 - option rake if you like soin
