## Determining Probabilities

When would you expect the experimental probability of an event to be closest to its theoretical probability? When the results of 10 trials were used in calculating the theoretical probability When the results of 10 trials were used in calculating the

## Statistics

Suppose that the probability distribution of a random variable x can be described by the formula P(x) = x/15 For each of the values x = 1, 2, 3, 4, and 5. For examples, then, p(x=2) = p(2) = 2/15 a Write out the probability distribution of x. b Show that
