    urgent probability question

    Hi guys, just about to head into an exam and i can't get my head around this one. Could somebody help me out.

    The probability that an individual walking across the goodwill bridge is a university student is 0.3. If 20 people walking across the bridge are sampled, approximately, what is the probability of finding at least 8 university students?

    Thanks to anyone that can help!!!
