¶ Stress  Strength Interference for two Normal Distributions Given the probability distributions for stress and strength, this module will find the probability of failure due to stressstrength interference. Failure is defined as when stress>strength. Uses the exact formula method which is only valid for two Normal Distributions.
Inputs: stress  a probability distribution from the Distributions module strength  a probability distribution from the Distributions module show_distribution_plot  True/False (default is True) print_results  True/False (default is True) warn  a warning will be issued if the stress.mean > strength.mean as the user may have assigned the distributions to the wrong variables. You can supress this using warn=False
Returns: the probability of failure
