Toss five fair coins and let x equal the number of heads observed. a. Identify the sample points associated with this experiment, and assign a value of x to each sample point. Then list all the possible values of x. b. Calculate p(x) for the values x = 3 and x = 4. c. Construct a probability histogram for p(x). d. What is P(x = 2 or x = 5)? a. What are the possible values of x? O A. x = 1,2,3,4,5 O B. x=1,2,3,4 O C. x =0,1,2,3,4 O D. x= 0,1,2,3,4,5
