I get confused when the question says "At least, more than, less than, at most", for example, "On average at all the schools in this country 30% of students do not like any sports: 10 of the students from this country are chosen at random, find the probability that at least 3 of these students do not like any sports"
Am I supposed to do P(0) + P(1) + P(2) + P(3) or is it P(0) + P(1) + P(2)
