    Find the indicated probability. Round to three decimal places. In a certain college, 33% of the physics majors belong to ethnic minorities. If 10 students are selected at random from the physics majors, that is the probability that no more than 6 belong to an ethnic minority?

    Probably I would be better able to stumble through this if I had a clue about how many physics majors there are. Isn't that a real serious consideration? What if there were only 10 physics majors? What if there were 15? What if there were 3,068?
    I would love to understand how to come up with a reasonable answer! You must know, since you posted the question in this category. If it is homework, or you need help, why not stick it in the HOMEWORK category?

    this cannot be answered as insufficient information is available. The total number of students must be known to be added to the equation.
