Unformatted text preview: Probability Examples 1. The experiment is to roll a six-sided die. (a) Write down the sample space S , that is, list all possible outcomes of this experi- ment. (b) Let A be the event that die shows a number that is greater than or equal to 5. Write down the outcomes in A . (c) Let B be the event that the die shows an odd number. Write down the outcomes in B (d) Write down the outcome(s) in the event A B . (e) Let C be the event that the die shows a 1. Write down the outcome(s) in C . (f) If all outcomes in this experiment are equally-likely, compute P ( A B ). (g) If all outcomes in this experiment are equally-likely, compute P ( C B c ) 2. Suppose that for a population of 100,000 individuals: 10% of the individuals watch Hockey and Football. 35% of the individuals watch Football. 55% of the individuals watch neither Hockey nor Football. The experiment is to randomly select an individual from this population and ask about his/her football/hockey watching. Let F be the event that the randomly selected individual watches Football. Let H be the event that the randomly selected individual watches hockey.the event that the randomly selected individual watches hockey....
