13. What is the probability that a randomly selected person is male OR prefers Burger King? 14. What is the probability that if two people are randomly selected, they both prefer McDonald's? Use the following information for 15 through 20. A bag contains 6 balls with the following colors: red, white, blue, yellow, green, and orange. You cannot see into the bag and all balls have the same feel, so the selections are random. 15. If four balls are picked out (without replacement), how many different permutations can there be? 16. If three balls are picked out (without replacement), how many different combinations can there be? 17. If two balls are picked (without replacement), what is the probability that one will be red and the other blue? 18. If only one ball is picked, what is the probability that is it n_ot orange? 19. If one ball is picked at a time (with replacement), what is the probability of picking the orange ball at least once in 3 attempts? 20. If all six balls are picked out one at a time (without replacement), how many different permutations can there be
