A probability distribution can be such as P(X) = 1/X, where X = 2, 3, 6. The distribution is notation 35. P(X) = X/7 for X = 1, 2, 4 shown as follows: 2 3 6 36. P(X) = X/(X + 2) for X = 0, 1, 2 P(X) 37. Computer Games The probability that a child plays one computer game is one-half as likely as that of play- ing two computer games. The probability of playing three games is twice as likely as that of playing two games, and the probability of playing four games is the average of the other three. Let X be the number of com- puter games played. Construct the probability distribu- tion for this random variable and draw the graph. For Exercises 31 through 36, write the distribution for the formula and determine whether it is a probability distribution. 31. P(X) = X/6 for X = 1, 2, 3 32. P(X) - X for X - 0.2, 0.3, 0.5 33. P(X) = X/6 for X = 3, 4, 7
