Let $R_k$ for $R_1, R_2, R_3... R_{10}$ be the cumulative inches of rainfall in year $k$ in Springfield. The amount of rainfall per year is independent of the rainfall during other years. On average, how many of these 10 years will have record rainfall? $\forall k \in [1, 10], R_k \sim Normal(\mu, \sigma)$ such that $\mu$ and $\sigma$ make it very unlikely for rainfall values to be negative.
Since each year is independent, would the answer be $10(\frac{1}{10}) = 1$?
