defective” mutually exclusive? Justify your answer. (3 marks)
e) Are the event “first camera drawn is defective” and the event “second camera drawn is
defective” independent or not? Justify your answer. (5 marks)
f) Use the appropriate multiplication rule to obtain the probability that the entire lot being

Question 1162207: One fine winter morning, you are walking your dog,Tootsie, in the park. Tootsie sees a cat. For the first 10.0 seconds, you hold the leash as tight as you can, and you manage to keep Tootsie in one spot. Then, Tootsie gets loose. He accelerates at 4.21 (m/s)/s. He reaches his maximum speed of 421.7 m/min. Then, Tootsie collides with the cat. The collision causes him to slow down at a rate of 3.50 (m/s)/s until he finally stops. Calculate the distance travelled by Tootsie from the time he saw the cat to the time he finally stopped. (Assume acceleration is constant.)
