Solutions to Homework 5 Problem 4.4 a. The tree diagram: b. The possible experimental outcomes are HHH,HHT,HTH,HTT,THH,THT,TTH,TTT c. Each outcome is equally likely, so the probability for each outcome is 1 8 = 0 . 125. Problem 4.9 Here we are counting the number of possible outcomes of choosing 4 objects from 50, where the order is not important. This number is C 50 4 = 50 4 ! = 50! 4!(50 - 4)! = 50! 4!46! = (50)(49)(48)(47) (4)(3)(2)(1) = 230 , 300 . Problem 4.19 a. For bicycle riding we have 21 127 . 6 = 0 . 165 . For camping we have 24 . 3 127 . 6 = 0 . 190 . 1
