Answer:
This is example of cluster sampling.
Step-by-step explanation:
The commissioner randomly selects 2 teams from all 30 MLB teams and has everyone on that team drug tested.
This is an example of Cluster sampling.
Cluster sampling is a sampling method, where population is divided into clusters and then each sample from a selected cluster is sampled.
Yes this is also a random sample.
8x - 2y = -8
-5x + 2y = -1
3x = -9
x = -3
The probability of the outcome of the color/ Divided by the total of how many colors there are.
in this case there is one yellow, but it may very well be smaller than the other colors so it does not have the probability of 1/4, unless they tell you that all the color sizes are equal.
so now, instead,we shall base it off of the Trial Numbers. Which would be 10/50, which can be reduced to 1/5. :)
Good Luck!
(But please ask your teacher or mentor if this is correct.)

Answer:
P(Hispanic or Bilingual) = 0.429.
Step-by-step explanation:
This question is solved treating these events as Venn probabilities.
I am going to say that:
Event A: Hispanic
Event B: Bilingual
Out of 14 teachers, 4 are Hispanic, 5 are billingual, and 3 are both:
This means that:

What is the probability that teacher is Hispanic or bilingual?
This is:

With the values that the exercise gives us:

So
P(Hispanic or Bilingual) = 0.429.
