If the chance of an overnight freeze in Rexburg on any given night is 0.5,
what is the probability it will freeze one or more of the next 12 nights in Rexburg?
~~~~~~~~~~~~~~~~~~~~~~~~ 

"If the chance of an overnight freeze in Rexburg on any given night is 0.5", then

    the chance of NO overnight freeze in Rexburg on any given night is 1-0.5 = 0.5, too.


Then the probability it will NO freeze at any of the next 12 nights in Rexburg is 0.5%5E12.


Then the probability it will freeze one or more of the next 12 nights in Rexburg is 1-0.5%5E12.

Answer. The probability under the question is 1-0.5%5E12.
