Question: A pediatrician records the number of ear infections that his patients have during the winter. A distribution of probabilities for number of ear infections is displayed below.
| Number of ear infections | 0 | 1 | 2 | 3 | 4 | 5 | 6 |
| Probability | ? | 0.16 | 0.25 | 0.33 | 0.15 | 0.04 | 0.02 |
a) Complete the probability of no infections to make above a valid probability mass function.
b) What is the probability that a patient has more than three ear infections during the winter?
c) What is the mean of the probability distribution?
d) What are the variance and the standard deviation of the probability distribution?
