## Lognormal Distribution Calculator

This calculator gives the probability that a random variable with lognormal distribution and given mean and standard deviation of the corresponding normal random variable, lies within the specified range.

Range upper and lower bound values must be greater than or equal to zero.

**Example 1**- Mean = 0, Standard Deviation = 1, Range lower bound = 0, Range upper bound = 1

Probability: 0.5000 **Example 2**- Mean = 0, Standard Deviation = 1, Range lower bound = 0, Range upper bound = +Infinity

Probability: 1.0000
