Answer:

She can choose her electives in 20 ways.

Step-by-step explanation:

The order in which she chooses the courses is not important, which means that the combinations formula is used to solve this question.

Combinations formula:

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

How many ways can she choose her electives?

3 electives from a set of 6. So

C_{6,3} = \frac{6!}{3!(6-3)!} = 20

She can choose her electives in 20 ways.

A bag contains some number of marbles. It is known that 20 of them are red. When 15 marbles are drawn, without replacement, we g
Llana [10]

Answer:

The total number of marbles in the bag is 50.

Step-by-step explanation:

Here, we have n trials, without replacement. So the hypergeometric distribution is used.

The mean of the hypergeometric distribution is:

E(X) = \frac{n*k}{N}

In which n is the number of items in the sample, k is the number of items in the population that are classified a success and N is the size of the population.

15 marbles are drawn:

This means that n = 15

A bag contains some number of marbles. It is known that 20 of them are red.

This means that k = 20, since a success is drawing a red marble.

Assuming E(X)=6 red, what is the total number of marbles in the bag?

We have to find N when E(X) = 6

So

E(X) = \frac{n*k}{N}

6 = \frac{15*20}{N}

6N = 300

N = \frac{300}{6}

N = 50

The total number of marbles in the bag is 50.
