a. Compute the mean number of accidents per day. \( \mu= \) (Type an integer or a decimal. Do not round.) b. Compute the standard deviation. \( \sigma= \) (Type an integer or decimal rounded to three decimal places as needed.) c. What is the probability that there will be at least 2 accidents on a given day? \[ P(x \geq 2)= \] (Type an integer or a decimal. Do not round.)
