Question 632572: In a survey, it was reported that 33% of women believe in the existence of aliens. If 100 women are selected at random, what is the probability that more than 45% of them will say that they believe in aliens? Answer by reviewermath(1029) (Show Source):
You can put this solution on YOUR website! X~Binomial(100,0.33)
Look for P(46 or greater) in the table below:
The answer is .
Note: The answer is slightly different if we use Normal distribution to approximate the probability. the answer 0.0046293 is exact because all the requirements of Binomial Distribution are satisfied to solve the probability.
