Given information
The distribution function is normally distributed.
The speed limit is 100 km/h.
The mean of the normal distribution is 112 km/h and the standard deviation of the normal distribution is 8 km/h.
Step-by-step explanation
Step 1.
- The probability density function of normal distribution having mean and standard deviation is given by .
- Write the probability density function by substituting 112 for and 8 for .
