In a certain college, 33% of the physics majors belong to ethnic minorities. Find the probability of the event from a random sample of 10 students who are physics majors.

The probability that no more than 6 students belong to a ethnic minority is 0.9815.

Step-by-step explanation:

The question is incomplete:

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?

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.

answer is because 4×10=40

and 98×4= is 392

40,392

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
