Step-by-step explanation:
<em>The question is incomplete:</em>
<em>In a certain college, 33% of the physics majors belong to ethnic minorities. If 10 students are selected at random from the physics majors, what is the probability that no more than 6 belong to an ethnic minority?</em>
We can model this with a random variable, with sample size n=10 and probability of success p=0.33.
The probability that k answers are guessed right in the sample is:

We have to calculate the probability that 6 or less students belong to a ethnic minority. This can be calculated as:




The probability that 6 or less students belong to a ethnic minority is 0.9815.
