Let me know if this is wrong.
Answer:
Depends. Check out the explanation below.
Step-by-step explanation:
Depending on which number you choose, you will have the same chance for each of them. To find out the chance of each of them, you first need to find the denominator, which is 6 because there are 6 sides of a dice. Now, we need to find the numerator. How many sides are we looking at? 1? 2? 3? Depending on how many sides there are, is your probability. So, if there is one side you are trying to find, it would be 1/6. If there are two sides, it would be 2/6 or 1/3. And so on.
Answer:
The expected number of interviews is 3.25.
Step-by-step explanation:
For each person applying for a profissional position, there are only two possible outcomes. Either they land an interview, or they do not. The probability of a person landing an interview is independent of any other person. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:

In this problem, we have that:

So

The expected number of interviews is 3.25.
Answer:
1 1/8
Step-by-step explanation:
3 * 3/8
9/8
8 goes into 9 1 time
8*1 =8
9-8 =1 so there is 1 left over
The left over goes over the denominator
1 1/8
Divide both sides by the GCF which is 8, so it is 3:7
