 Posted - 09/18/2007 :  07:37:21 Hi, I need to know the probability of exceeding a specific value when the change in the value is distributed normally. For example, suppose a toy car costs initially 10\$. Now, the value of the car changes with normal distribution, i.e. with zero mean and variance of one.I need to know how to calculate the probability of the car costs over 13\$. Moreover, how to calculate the time estimation for this to happen (I guess the time scale is derived from the rate of change in the value)? Can anyone help?
