Help me please? How do I solve this?

You operate a restaurant. You read that a sample survey by the National


Restaurant Association shows that 40% of adults are commited to eating nutritious


food when eating away from home. To help plan your menu, you decide to


conduct a sample survey in your own area. You will use random digit dialing to


contact an SRS of 200 housholds by phone. You find 100 of your 200 respondents


concerned about nutrition. What is the probability that X is 100 or larger if p=0.4 is


true?

Reply:0... you only heard from 100 of your respondants... how can more than 100 of them want to eat healthy?
