Answer:

6 students are wearing shirts that aren't blue or white

Step-by-step explanation:

1/6 + 2/3 = 5/6  

5/6 are wearing either blue or white so 1/6 isn't wearing blue or white

there are 36 student and 1/6 means 36 divided by 6

Svetllana [295]

Answer:

You would expect for 35 people to have consumed alcoholic beverages.

Step-by-step explanation:

For each person, there are only two possible outcomes. Either they consumed alcoholic beverages, or they did not. The probability of a person having consumed alcoholic beverage is independent of any other person. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

Probability of exactly x successes on n repeated trials, with p probability.

The expected value of the binomial distribution is:

E(X) = np

We learned in Exercise 3.25 that about 70% of 18-20 year olds consumed alcoholic beverages in 2008.

This means that p = 0.7

We now consider a random sample of fifty 18-20 year olds.

This means that n = 50

How many people would you expect to have consumed alcoholic beverages

E(X) = np = 50*0.7 = 35

You would expect for 35 people to have consumed alcoholic beverages.

Answer:

3/6 or 1/2

Step-by-step explanation:

y2-y1 = 8-2 = 6

x2-x1 = 3-0 = 3

The point would be (3,6) or if simplified (1,2)
