State features of normal distribution. In a photographic process, the developing time of prints as a random variable having normal distribution with mean of 18.25 seconds with standard deviation 0.34 seconds. Find the probability that at least 17.64 seconds to develop one of the prints.

- Bell-shaped and symmetric about the mean $\mu$; the two halves are mirror images. 2. Mean = Median = Mode, all located at the center $\mu$. 3. Completely defined by two parameters: mean $\mu$ and standard deviation $\sigma$. 4. Total area under the curve equals $1$ (total probability = 1). 5. ...
