The Professor's Response

hi professor, im having some trouble with a binomial random variable question and I was hoping that you could clarify. the problem is as follows P(170 less than equal to x less than 180) when n = 600 p = .3 I know that the mean is 180 and the standard dev. is 11.2249
but is it as simple as just finding the area from 170 to the mean or am I over simplifying ?

  See the professor's answer below.

Professor McGukian

That's correct Jose! You would add the 0.5 to avoid taking any of the 170 when you calculated the area.
