      Note: 0.25 was found by looking in the standard normal table for a probability near 0.10. This value is between 0.25 and 0.26 standard deviations above the mean; we choose 0.25 because it is the closest. In fact, the normal approximation doesn’t help answer this question exactly, as shown in this Excel spreadsheet: 17.

      Standard_dev is the standard deviation of the distribution. Cumulative is a logical value that determines the form of the function. If cumulative is TRUE, NORMDIST returns the cumulative distribution function; if FALSE, it returns the probability mass function. The equation for the normal density function (cumulative = FALSE) is:
