Answer:
The probability that no more than 6 students belong to a ethnic minority is 0.9815.
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.
Answer:
look down + pls give me brainiest
Step-by-step explanation:
Let x = number of people when she got on.
x -4+3 -5+1 -1 = 4
x -6 = 4
Solve for x to get x=10.
So there were 10 people when Paulina got on (including herself).
A/b *100
For example,
30/600.
30/600=0.05
0.05*100=5%
Lets look at it as the Pythagorean theorem, so A²+B²=C²
First step: find the X (a) and the Y (b)
|6-0| = 6
|-4-2|= 6
Second step: 6²+6²=c²
36+36=C²
72=C²
√72=√C²
8.49=C
your final answer would be 8.49 units
